Tombstone Diesel is the premier shop for anyone looking for the best service and the best Quality. Travis is the absolute best to work with. My truck was done on time.. actually a day early, and the attention to detail exceeded my expectations. I was not over sold anything and He went the extra mile in every aspect of service. I Highly recommend Travis for anyone looking for a honest mechanic and quality shop to work on your vehicle. Thanks again Travis!!!!

Just dropped my 2012 duramax off. Very impressed. Clean shop, the guy is very knowledgeable and easy to talk to. Trust me, dont go anywhere else. Take the time and make a appointment and get it right the first time.

If you’re looking for a quality shop with a great mechanic I highly recommend Tombstone diesel and Travis. I can not say enough about Travis and his work and customer service. He takes the time to listen and understand your needs and then explains what he feels would be the best solution to your issues and needs. He quotes you a price that is fair and then he delivers. I had multiple things done to my duramax including an efi live tune on the tow mode. This has made a world of difference on how my truck now tows my fifth wheel. The shifting under load is so much smoother and I’ve actually seen a slight gain in fuel economy. While performing the work he came across things that could be cleaned up and rerouted which he did. His attention to details is in my opinion one of the things that sets him apart from other shops and mechanics. I traveled over 100 miles to have Travis work on my truck and can’t be happier. This will be the only shop that I will visit from now on. I highly recommend Tombstone diesel to anyone in need of a great diesel shop. Thanks TravisPaul 05 GMC Duramax

I took my 2003 7.3 powerstroke to Travis for a few upgrades and maintenance issues and he knocked it out of the park! His attention to detail is evident and he went above and beyond to ensure I was going to be happy with his work. In short, he made me happy with my truck again! No need for a new truck when this one feels like it now! If you have a diesel, you need to talk to Travis.

I really love the way this shop is run; it is the only place I will bring my truck from now on. I have been to many different shops across the country and this one tops them all. The owner keeps you constantly updated and will go above and beyond to help you reach your goal. From trans work to tuning he does it all in house. If your truck is your pride and joy like mine is to me, you will be happy to know that it is in good hands from the moment you enter the shop. I cant wait to get my rig back in there for a couple more upgrades. Other shops need to start taking notes!

Looking for high end diesel work done on time, at a reasonable price, from a super cool guy with integrity who really knows his stuff? Look no further. Travis is your guy. He just completed a BD exhaust brake install on my 2nd gen Dodge, and a steering upgrade. Brilliant work and he was kind enough to work late last night and was done a day early because theres a snowstorm coming in. Travis does work on way higher end motors and gear than my beloved 2nd gen 5.9 - so bring him your biggest challenges. I got her back today and immediately booked my Dodge in for a leveling kit a couple weeks from now. As I said to him earlier today, my only regret leaving this 5 star review is Im worried he may book up for all the work Im going to send him over the next few years. Im sure youll have the same great experience Ive had, and all the other 5 star reviewers here have had. I strongly recommend Tombstone Diesel Performance for all your Diesel performance needs.

Best diesel mechanic ever!! Replaced our engine, fine tuned to enhance performance. Sent pictures of the progress and kept us informed. Highly recommend for any diesel work. Travis goes above and beyond all expectations.

I run a hotshot company. I was coming through the area when I thought my exhaust manifold was leaking. I stopped in and the first thing I noticed was the cleanliness of his shop. To me it showed he had pride in his place. He had other stuff he was working on but still took a second to look at my truck and diagnosed it in 30 seconds. And in 10 minutes had it fixed and ready to roll. Didn’t even want to let me pay. It will be a much nicer ride back home to Texas! Thanks so much for your help!!

I bought a BD transmission from Travis after my old transmission quit in my 2005 Dodge 2500. I usually dont get things done at shops because I can usually do everything I need to on my vehicles. I decided to go with Travis and Tombstone Diesel because Travis is a certified BD Transmission installer and can also service them as well. I have no doubt I made the right decision. Keep up the good work Travis.

Awesome travis really knows what hes doing fast clean

Travis just rebuilt the motor on my truck and did an excellent job. Not only did he take the time and care to make sure everything he did was perfect, but he also addressed and fixed several other issues that I had not known to be there. If you need a good diesel shop Tombstone Diesel is definitely the place to go. They do great work and are very meticulous. My truck is running great!

I am glad I got referred to travis. Just bought my 07 mega cab and my injectors went out. After travis did his magic to my truck, the truck rips. I will not take my truck to anyone else. Have more to do to my truck and cant wait to see what travis has in store for it. Thank you travis and I would recommend everyone I talk to, to go to him

I am 70 years old and have had a number of experiences with mechanics. To say the least Travis is the absolute best. His knowledge is beyond his years. His attention to detail and his professionalism is second to none. I have never been overly impressed with mechanics but now have found The Best in the state of Colorado. If I lived on the western slope I would make the trip to have him work on my truck. That is how much I think of him. If you want the very best in service, professionalism and attitude (Extremely nice man. Almost to a fault) you cant go wrong. Even though he is a one man operation, its to your advantage, as there is no one out there will give you the attention to detail like Travis. Make a new friend with him you wont be disappointed.

Everything I expected and more! Great honest service thats much appreciated and affordable. Travis is a stand up guy that gets the job done as he tells you he will. My vehicles will be in good hands from now on.Thanks for everything Travis!Jake Boswell

Travis is the best of the best. His attention to detail is to the point of perfection and he wouldnt do it any other way. I happily make the 3 hour drive to bring him my truck because I know it will get done the right way. Travis and Tombstone Diesel has earned my business for years to come.

Best diesel guy you could ever know! If you want quality work you will not be disappointed.

Travis is probably the best diesel tech in Douglas County. His attention to detail is top notch

I can’t say enough good things about Travis. We have 3 diesel pickups which Travis totally rebuilt the engine in one of them he does things right and is truly the most honest mechanic you will find. We don’t take our vehicles anywhere else. Love this place trust me you won’t go wrong choosing this shop.

Love this place! Travis is a great guy, and literally blows my mind because he is a magician with diesels. I’m glad I finally found somebody and a place that has pride in their work and I can trust is always giving me the right information, And fixes it right the first time. Wouldn’t go anywhere else!! Thank you Travis!

BEST OF THE BEST. ! Got a new BD turbo and intake and tune . They were honest and on time with everything.. Thanks. CE

Cant say enough about the unique combination of knowledge and integrity. Not sure I want to share him with anyone else! Although he does a lot of go fast installations, hes been a wealth of knowledge with my 97 Powerstroke (495 k miles and counting) and my sons 01 Dodge 3500. Take a shot, you wont be disappointed!

Travis with Tombstone Diesel is a top tier diesel mechanic. He’s very knowledgeable about each platform. He was very patient, listened to my concerns and answered all my questions respectfully. My long search for a diesel mechanic I can trust has ended. Travis has all my business as well as my referrals. Dude knows his stuff. You should give him a call.

Tombstone Diesel service is awesome.Travis is extremely knowledgeable and professional.I recommend you talk to him about your service needs and or performance upgrades.Thanks again for the work on my truck.

In todays environment its pretty challenging to find honest, high integrity, meticulous work. Travis is someone who represents all of these qualities and understands that creating lifelong customers is an authentic way of growing business. He actually cares about the products, work and integrity which is why he creates raving fans. I feel blessed to have met him both personally and professionally after several instances. I run a few different trucks, a Cummins and Powerstroke and he has done miraculous work on both. Hes a great contact to have no doubt!

Had an awesome experience working with travis. He helped me figure out what the best option was going to be for my truck. Was able to schedule my truck to get in just a few days after parts arrived. I dropped my truck off at 2 oclock on a Wednesday and picked it up the following day. Extremely quick work all while paying attention to the smallest things. I couldnt be happier with my new BD trans and torque converter. You cant get service like this anywhere else.

Awesome shop, they dont treat like other diesel shops in the area...cough cough...douglas county diesel...who just talk to you like you know nothing about trucks. All I needed was to have my fuel tables reset, was done in a few minutes. Noticed my fuel filter was leaking and even helped me out with it. Couldnt beat the price either.

Travis has worked on several of our vehicles and each time left them better than we could have ever imagined. His incredible knowledge and apparent natural intuition of diesel performance makes him, in our opinion, by far the best in his field and the only person we trust to do any work for us.

Travis is great to work with, professional, knowledgeable, and honest. I have taken my Cummins to him on two different occasions. The work he performs is top notch and performed with extreme detail. I would highly recommend using Tombstone Diesel to anyone looking to get the job done correctly.-Brad Adamson

Travis is incredibly knowledgable and ethical. Whatever you use your truck for, hes the guy to go to. A one man shop, hes got his own hands on your vehicle, and goes out of his way to offer great service. I can not recommend him highly enough. Its been a priviledge to know him and work with him. His attention to detail is second to none, his workmanship immaculate, and he has fun doing it. What a pleasure to find somone who has such great values and customer care. He is a friend in the end.

I have owned my Dodge ram for about 16 years now and have struggled the entire time with finding a trustworthy and competent diesel mechanic in the Denver area. Ive been to several places in the Denver, Parker, and Castle rock area. Some did a fairly decent work, and work done by others ended up being pretty poor - or at a minimum questionable. Fortunately, my truck hasnt required much maintenance attention over the years, but when it does, I want to have confidence the work is being done right, and I am not being gouged or up-sold on a bunch of stuff that doesnt need to be done either with the engine, or other areas of the truck.I ended up needing some work done on my truck last month (engine, exhaust, and drive train), and I started asking around for recommendations from friends I trust since I didn’t have a lot of confidence in the shops I’ve used in the past and preferred not to use any of them if I didn’t have to. Travis at Tombstone Diesel was recommended to me by a friend of mine who himself was a diesel mechanic for a number of years.Every aspect of my dealings with Travis and Tombstone Diesel was completely top notch, from Travis’ good communication and responsiveness to my initial email to schedule an appointment, to the bumper to bumper inspection of the truck and his very honest and realistic prioritization of what definitely had to be done, what would be nice to get done, and what might need to get done “someday”, to the pre-work estimate, and all the way through to the work being completed. I was informed and in the loop the entire time.As most diesel owners know, they tend to be expensive to get parts for, and mechanic/technician labor rates can be quite high. What Travis charges is very reasonable - especially considering the quality of work that I was very pleasantly surprised to find out that he does. Hes the kind of guy who, if he tells you something needs to be done, you can actually trust that hes being honest, and not trying to simply get more work and money out of you.Travis is definitely a straight shooter, which I absolutely appreciate at this stage of my life where I have no time or patience for slick salesman nonsense - been there and done that for sure, and that has been a problem with some of the past diesel shops I’ve used over the years, which is why I no longer go there.Last and certainly not least, the attention to detail and quality of the actual work done on my truck is some of the best I’ve ever experienced. Again, my truck is about 16 years old at this point and it runs and drives better now than I can ever remember it running and driving… even my wife noticed (go figure).Oh - and this snowstorm we had last week made it so I was not able to come down and pick up my truck during the week like I intended to once his work was done (which he completed on schedule, by the way). Travis made a special trip to meet me at the shop over the weekend so I could get it. Top notch customer service right there.Anyway, suffice to say that I feel extremely fortunate to have found Travis and Tombstone Diesel, wish I would have known about him sooner, and without question, any future work done on my truck will be done by him. He legitimately comes with my highest recommendation. I wish I could give him a 6th or 7th star... I suppose a 5 star rating will have to do. Thanks a bunch, Travis!

Glad to finally have a place I can recommend to my friends and trust I won’t be let down. Travis knows his stuff, we have Dodge and GMC ranch trucks that we use hard and depend on everyday and I wouldn’t take them anywhere else!

Get to know Travis, a diesel Truck owners best friend

Travis is a very honest and experienced mechanic. Whether its a grocery getter, or built for the race track, he is the man to fix it right!

One of the most honest and professional mechanics out there.
