Great experience with Dead Horse. I lost 2 vent covers on my trailer on my way into town and it was hot and stormy. They opened their store after hours and during their move to help me out. Definitely good people, highly recommend their business.

Edited Review:Please do not get work done here. They employees do not know what they are talking about. Randee didn’t even know the difference between a deep cycle battery and a starter battery. They are extremely unprofessional and rude to their customers. They will not admit fault and are over charging us for their mistake. We were supposed to go get more work done but decided against it. When we said the battery was on the right we meant from standing in front of the vehicle. As a professional you should have clarified passenger or drivers side. You should also know the difference between a house battery and a starter battery, they are completely different. You said you called to see if you should test it.... why would you do that when testing it takes less time than contacting the customer. We may have said right side but we also said “house” and that is pretty evident which is which considering one says “deep cycle” on the side. The deep cycle battery you replaced it with from o Reilly cost LESS than the starter battery we paid for. You are lying to us about the cost and we should be getting a refund. We were originally quoted $120 for a deep cycle battery from your receptionist and then was told you “upgraded” us. The second mechanic we hired said you overfilled the oil and didn’t even tighten the battery. Overall I recommend taking your business elsewhere. Difficult to communicate with and not trustworthy.And if the deep cycle “house” battery does cost more than the starter battery PROVE IT. We asked for a receipt and it could not be provided. I went to o Reilly, I know the prices and I know you guys are not being truthful.Why would I ever go around the country doing this. This did not benefit me in any way. I only have two google reviews and none on yelp. Unfortunately this was the first time has happened to me and hopefully no one else has to experience. Very weird accusation. People can see how unprofessional just by reading your responses to reviews. Good luck.

Nice people but over charged. Yeah in response to waiting 7hrs, your shop Forman informed me of you having to hunt for a starter for your previous customer who was stuck in Phoenix. So thats why you couldnt fix my issue in the time frame you gave me. I wonder did you charge them extra for that or am I paying for both jobs 🤔.

Needed to add plumbing to allow the use of external propane tanks for extended boondocking. Apparently since the kit on the shelf didn’t fit, the other two rv dealers in town “couldn’t” do it. Mitch at Dead Horse assembled the necessary plumbing and got it done same day. Very “can do”, not your typical slick rv money grabbers. The guys at Dead Horse Diesel and R.V. are ethical and do good work at a fair rate. They definitely went above and beyond. Give them a call.

We had our oil changed today, and was done in a timely manner. We appreciated their good service. Thank you!

Broke down in our 2000 Fleetwood Bounder on I 40 about 10:00 AM on Friday the 7th of May. Water spewing from the radiator. Limped it to a truck stop and filled the radiator. Found Dead Horse Diesel on Google and made it to Cottonwood, AZ. Mitch diagnosed the radiator as a lost cause. He and Heather worked like mad calling all over the country to find the part. Found it in CA and arranged the shipping. They helped us get set up in a campground to wait till Tuesday. Tuesday came and the part did not. Shipper failure. They provided us power and let us camp in their shop parking lot since the radiator had already been removed. The radiator arrived on Wednesday. The Mechanic was waiting on it and jumped to the work. They had us on the road by noon. Dead Horse Diesel and RV went above and beyond to take care of us. Mitch and Heather worked miracles and made sure we were taken care of at every turn. Thank you Guys. You ROCK.

Sorry for the 1 star my 7 yr old was playing with the cell phoneThis is a great place thay were very professional

We are brand new to the rv world, this was our first rv adventure and we ended up having to get help. We tried our best and it wasn’t working. We called Dead Horse diesel and rv repair, they arrived within 30 minutes and got us starting our adventure. We were embarrassed to have to call but we had no choice even the campers around us couldn’t help us. They were understanding, showed us the problem, which wasn’t our fault, woohoo! While here they gave us good tidbits and even tried to help a fellow camper that unfortunately locked their keys in their car. During Covid customer service went to trash and so did friendliness but not at Dead Horse Diesel and RV! Thank you for helping us and saving our adventure!

Lost Braking Air Pressure along I-17N FMCA RSA sent Mitch as the Mobile RV Service. The Team, Mitch Tony and Josh quickly determined One of the Air Tank Pressure Relief Pop Off Valves had a slow leak. Also one of the Air Bag Leveling Arm had broken and the Coach was leaning. We ordered the parts when they came in they were installed that day and I was on my way. I own William Thomas Mattress Gallery in Cwd. I am Local. I dont know what or why some of the bad reviews. My experience was great. I know Ms. Heather must be a great Mom, she had the patience of Job with me as we found the parts and waited . She understood this Motorcoach was my Million Dollar Baby, Retirement Gift. A Foretravel IH-45. Bottom Line they did good by me. Thanks so much everyone.

We were stranded on the highway for 4-5 hours, talked to Shannon, the mechanic.....in the conversation we felt this would probably be a good place to have our pickup and 28’ trailer towed to. We were right, they definitely helped us, we parked our trailer there, Shannon said our pickup WOULD get fixed and it did! We were towed there late one night, they diagnosed it the next day, had to drive to phoenix to get the part, and he got it fixed about 7:30 that night and we left early the next morning. We are grateful for their help!! Plus they recommended we call Johnson’s Towing which was good!

Great people working here. Took care of us. We had any emergency breakdown and they repaired our trailer. Highly recommend.

Our rear airbag line had broken and I did a repair alongside the road. When we arrived at our RV spot I noted the airbag was not holding air. DHD arrived and quickly deduced that the air line was not pushing into the airbag valve far enough. They fixed the issue and used some zip ties to make sure the airline stayed in place. They were both very friendly and the price charged was very reasonable. I would highly recommend their service.

Sent a roadside assistance, had no clue what they are doing. Didnt fix the problem, but had no problem to charge a fortune for nothing, $2500 to replace one air dryer hahahaha

My husband and I are on the road traveling from Montana to Texas trying to get home for Thanksgiving. We noticed our camper was burning through tires so, we called around town looking for a mechanic to check it out for us. Mitch and his team were the only RV repair place that would even get us in within a two week time frame. Our camper had bent axles and a list of other tire related problems. It was going to take 8 weeks just for parts to arrive. Within minutes Mitch came up within an idea that was faster and saved us money, he built a new suspension system. Not only that, he did it within 4 days so that we could get back on the road in time for Thanksgiving.We cant thank Mitch and Kendra for their kindness and hard work. Innovative and thoughtful.

ReviewTLDR: I haven’t seen Mitch own up to a single mistake. When people leave him an honest review, he spins it around to make the customer seem like the bad guy. They never once apologized for the mix up. 0 STARS. Worst customer service I’ve ever received. Read my friend Lauren’s review for the whole story.Basically, they replaced the starter battery on our camper instead of the house battery. I will admit I wrote on the Pre-work order that the battery was under the hood on the right. However, “the right” is subjective yet they assumed it as meaning the passengers side without even clarifying. I also stated on the work order AND over the phone that to my knowledge, courtesy of O’Reilly, our HOUSE battery was unstable. Reminder: house and chassis batteries aren’t even the same type of battery! House vs chassis is not subjective, as they are wired differently in the vehicle and perform two entirely different functions. Yet they replaced a perfectly good starter battery instead. When I expressed my concerns that they had changed the wrong battery, I was told over the phone that they were sure they had replaced the house battery and that “[they] are professionals, [they] do this for a living”. What professional takes a perfectly GOOD battery out of a car?We went back in to have them fix the job and they told us the deep cycle battery was $100 more than the other battery, trying to make it seem as though they are doing us a favor. But we know they get the batteries from O’Reilly and the deep cycle battery with the same part number is $100 at O’Reilly, whereas a starter is usually $120+. I would not have written this review if it weren’t for the fact that I know they are being dishonest about the price. Mitch will not provide proof for how much they paid for the second battery, nor will he provide proof of how much WE should’ve paid for the battery. I can only assume that’s because they don’t want to be caught in a lie!Now they are trying to accuse my friend and I of going around the country and doing this to lots of people?!? Mitch, you are delusional if you think that’s the case. We simply want evidence of how much you paid for that battery because it’s not cool to scam people. Based on the other reviews here, I think I can confidently say that YOU are the one doing this to people from all over the country. This is the first mechanic we’ve seen since we started traveling a few months back. Stop taking advantage of people who are entrusting you with their vehicles that are often, as in our case, also their homes!!!Not only are they being dishonest about the price, when we first addressed the mix up, they were incredibly rude, defensive, and dismissive instead of simply owning the fact they made a mistake! As a business owner, you should always first assume the customer is right! Because in this case, I, the customer, was indeed right, yet I was patronized multiple times by multiple people working at this establishment.Be cautious about giving these guys your money! There are other mechanics around town that will do a better job for a much better price.

There is a speed bump at entrance, with no warning signs or yellow markings; very unsafe! I hit bottom with my new car and was told it was RV park issue, not Dead Horse Diesel issue.

Warning these guys are a giant scam company!! They tried so hard to get me to pay them cash for a warranty job and lied over and over. When they finally got caught by the warranty company in their scam they finally brought me my part then refused to do the work!! The job was super easy and they quote of 3 hours to do the job was a total lie it took me 20min to replace and I’ve never done it before. They claimed for weeks if I just paid them directly and didn’t do a claim the job would be done much quicker?!? Don’t use these fools they should all be arrested and go to jail for running a scam service!!

If I could put 0 I would!!! how are you guys still in business ???Mind as well make sandwiches rather then doing repairs

Just like other reviewers, this place came to the rescue when we were in a tight spot. They straighten a damaged slide out bracket and refused to charge me. Thanks for the help!!

What a great shop! Deadhorse diesel has done multiple professional jobs as well as some personal jobs on our food truck and campers. This gem of a shop is the best around. Check them out next time you are vacationing here or are a local needing service. They definitely go the extra mile and are affordable as well!

Small rv parts and supply shop. Family owned and helpful

Mitch and his helper came out and did a great job on our RV tune-up. Even completed the job at lower than quoted price. They were able to come out very quickly when I called, and completed everything in a timely manner.

Ive called Dead horse Diesel a few times now for our R.V. needs. They were prompt, efficient and professional! Very reasonably priced. They are my go to company for all of our R.V. needs!

I found a very remote camping spot off FS525C north of Cottonwood to spend a week. When I went to start my Mercedes Sprinter 3500 diesel, I smelled diesel, popped the hood, diesel was spraying all over the engine compartment. After calling every possible company that might help me, Tyler Facey from Dead Horse RV called me back. When I explained my problem, he said he would know what was wrong within 5 minutes of getting there. He said this so convincingly that I agreed to hire him/his company. Once Tyler arrived he found the problem in less than 60 seconds. Pack rats had chewed through the high pressure diesel fuel lines. Tyler told me he could fix this. He had to improvise with fittings and hoses as it would not be practical to get these parts from a Mercedes dealer. On a 1 - 10, Tyler is a 20. This guy is a brainiac diesel mechanic and probably much more. He saved the day. THANK YOU TYLER!!!update 4.22.19We went back out FS525C, found a very private spot to camp for 4 days, on the way back out, the spare tire rack/holder was ripped apart by rocks, the spare tire fell to the ground. After digging for an hour I was able to get tire out from under van. I duct taped tire rack/frame together, limped back to Cottonwood, pullled into Dead Horse Diesel and RV, asked for Tyler. He quickly assessed the problem, made repairs to spare tire rack/frame and had us back on the road within an hour. Tyler saves the day, again. Thank you Tyler!

Charged over $1400 for a service call to replace an alternator. Next day we were back at a different shop because of a squeaking noise and some other repairs to the truck. We were told that the alternator that Dead Horse installed was defective and making that noise. We requested a repair invoice and a receipt so we can warranty the alternator. Its been a week and I cant get either. I have reached out to Rush Truck Center in Flagstaff to see if they can help with the Alternator warranty.Stay away or get burned. We had to pay twice for the same repair and made numerous requests just to get a repair invoice. No Luck. They were quick to grab payment but now want nothing to do with us or the faulty part they installed on our truck.

Love these guys. I wont go anywhere else for service! My sister drives from flagstaff for these guys, they are that good.

Needed my RV serviced and they did an excellent job! Fair, dependable, affordable and trustworthy. Couldn’t ask for anything more.

Fantastic service and help. Pulled in an hour before closing with a retractable step on Sprinter RV that was going to fall off after bottoming out several times. Owner and Randy stopped what they were doing and repaired the step jn less than an hour and then looked at electrical problem free of charge well beyond closing. This place is honest and competent - poor reviews do not fit with my experience at all. Very grateful for the emergency help and a pleasure meeting these guys.

Went in to order part for RV....they were great helping to find correct part and said it would be in 3 days. Well, a good week later they said not in and they will pick up part from another supplier when out on road. Finally got part in the day b4 im leaving town, now charged $144 for part I can get on ebay for $35! Kind of stuck so paid the ripoff price. Do you homework b4 ordering from these folks.

Very happy with the service I received, needed A/C work on my 5th wheel my family is living in, the owner dropped everything ran all the way to Phoenix and back to pick up the unit I specifically wanted, installed the A/C unit in no time at all, and at one hell of afare price. Thanks for helping a dude in need.

Very nice people and great service

Super place! Mitch and his great staff helped me get the right parts for older toilet and faucet repairs, very knowledgeable and thorough! If i have diesel issues, DHDRV will be my first call!

I will be back if I need something done he is very laid back easy going and very helpful and prices are very good to and I would recommend him and his staff to anyone that needs work done Ill be back for anything I need done when I come through this way

Great company to work for puts his customers and employees needs above his own

Mitch is very helpful and I would recommend him to anyone he will go out of his way to help you when you need it and made you feel like family and along with staff to

The store looks amazing. The customer service was on point answered every question I had with no issues and even told me how to fix my screen door myself so I didn’t have to pay someone. For a girl that is a huge bonus. Will definitely be back. Thanks Steve for the help.

Very reliable diesel service that goes the extra mile to get it done! 👍🏻

Dead Horse diesel and RV (AKA) Dignity Diesel Just move their shop from one end of the town to another Just change their name conveniently but has the same reputation and I would not trust them to do any work on any vehicle. Maybe Andrew was a Customer of Dignity Diesel thats why you cant find any records. How are you going to resolve our problems Mitch?

Bad service bad experience and rates are too much high and they charged me $800 and didn’t nothing to my truck because my truck got same issues and they told me take your truck to the dealership and when I asked them why you guys charged me that higher because my truck got same problem you guys didn’t fixed it than they hold my truck keys and told me pay what ever bills or you don’t get your truck keys back SO PLEASE DO NOT CALL THEM FOR SERVICE

Loved it. Beautiful area. Clean campgrounds. Very friendly.

Don’t take your truck there! Try came out on road service hooked jump cable to the battery and charged us about $600 for 2hrs and left us there.

With a loaded over the road tractor trailer broken down on a Saturday, I took a recommendation from a fellow OTR driver and called Dead Horse Diesel out of Cottonwood, AZ. My call was returned in minutes and a knowledgeable tech named Mitch diagnosed our issued with one picture and responded quickly. Repair was completed on site and charges were clearly explained and very reasonable. Nice work Mitch !

Mitch and his team were great! My baby needed over $30k in repairs after I ran into a tree (people make mistakes), and he didnt just fix everything, he pointed out legitimate problems I hadnt spotted, AND he found every way he could to shave a few bucks off the repair while still doing everything top-quality. Im forever thankful to him and his guys, and they even shared their pizza with me! The wife and I will definitely be back if we ever have trouble again (or if I ever decide to kill an innocent tree again with my stupidity)!

Amazing service and friendly staff! We own a company and use our cargo trailers all day everyday, one of the back doors broke and these guys not only fixed it once but twice and did a fabulous job! Would highly recommend

These guys were amazing. Not really understanding these reviews that were left on here. Mitch communicated with us through the entire process of our RV repair while we were broke down at Dead Horse Ranch State Park. Tyler was an amazing young man and very funny. Steve-o the office manager was very kind. These guys were so polite took off their shoes before entering our RV put cloth down so they did not get dirt anywhere. Every price was discussed and options so that it was always known here we would be at cost wise. these Guys were such a blessing and lifesaver. I would trust them anytime.

I had electrical issue with my motorhome.. diagnosed problem and fixed it correctly. Reasonable rates.. excellent service!

Incredible tech service and very honest..he answered by cell call immediately and fitted us in for a full day of intensive on site much needed work..this companies owner Mitch did all the work himself with helper Zach..I observed everything as he removed the entire sagging underbelly of a 40ft 5th wheel and located and repaired a hydraulic leak, added full width supports, and dozens of self tapping fasteners for the remounted belly, and multiple other repairs..very well skilled, modest price ...dont hesitate to call them for ur onsite repairs..A++++..oh, at the end of the project he brought over his dog and 5 yr old son Mason..I would have taken their photo but I was writing this review..lol

Great, fast and friendly service on Mothers Day of all days to replace our RV converter. Did come at a price, but it was a holiday.

I would leave no stars if I could. This place is a joke. Sent a 18 year old kid out that has never even been to mechanic school to fix a 18 wheeler. Threw a diagnostic test on it swore it was a fuel pump told us 5,000 for the fuel pump 8000 all together for bill. We told them nope because I called and verified parts prices and 2499 was the cost of the fuel pump. Thank God we took it to freightliner because was not even the fuel pump wrong. So 1000 dollars later its fixed and fixed with the right part.

This shop is a total disgrace to the trucking industry`s hard working driver & companies .They charge us $1100 for a coolant reservoir that was only $400 from the dealer & they won`t even provide us the receipt for the part when we asked for it . paid $4500 for a road service call to replace the coolant reservoir & a hose including parts & labor .Stay away from this shop that are there not to serve you fairly but to take advantage of you to the extreme

If I could give 10 stars I would. These guys are great!

AVOID! AVOID! THEY CHARGE 950$ FOR CLOSING THE VALVE AND PUTTING 10 GALLONS OF COOLANT ....AVOID !!!!

Mitch Peterson sold me a Jasper engine and just stole the money. He never even contacted Jasper, he just tore my motorhome apart, stole the money and left it that way. This is his modus operandi, steal the money and leave the work undone. He has been sued over a dozen times for ripping people off. Hes a predator preying on the community. Look elsewhere.

Charged over $2400 for a service call to replace alternator, .

These are straight crooks. Please run away!! If you pay first, you’ll never see the work get complete. If you don’t pay first, they will nickel and dime you to death to rack up your bill. Either way, your screwed!! Mitch Peterson is a very dishonest person.

Propper business ethics

Great service

Worst place crooks over pricing

Charge 800$ for change tire AVOID

Charged a friend $7000 for some work and gave him his truck back in a box with no refund. The guy is a total crook.

Ordered a toilet for our RV. Service was fair.Might go there again for parts .Might not.

That is a lie we were never provided with the receipt of the coolant reservoir itself & was not told that cost of it was $1100.We have the receipt of the full amount of the repairs .There is no way that coolant tank was $978 as we called the Volvo dealer in Phoenix & they told us the price was about $400

Best place in Cottonwood!

Over pricing !!!!!!!!!!!
