Full Integrity

In a state where the diesel industry is ever growing, we realize that you have the power to choose from a number of shops. We would like to tell you how much we appreciate your business and would like to take the opportunity to welcome you to the Tombstone Diesel Family. For many diesel shops, the primary goal is bigger, stronger, faster. Unfortunately, what most people overlook is that without the proper foundation, repair, and strategy even the best ideas can result in blown up engines and mechanical failures. Despite what many people think, diesel repair and performance are not simply about bigger, stronger, faster. Those are the building blocks that top the foundation of the complexities of the diesel engine and they require the highest caliber of service and repair in order to create the most powerful and reliable results. At Tombstone Diesel we believe that performance is only as good as the foundation it is built on. We believe that diesel repair and performance should be built on a platform of precision, knowledge, and quality. By laying this primary expertise, we are able to service, repair, and build diesels with additions and modifications that are built to last and withstand power.

Timely, Efficient, and Detailed

The Diesel engine is a complex and intricate design which consists of millions of moving parts. This is one of the reasons why we believe that focus and dedication to one job at a time provides the utmost of care, precision, and quality. When you entrust us with your diesel, you and your vehicle will receive quality care, attention, and customer service. No high volume shop mentality where things go unnoticed or names are forgotten. At Tombstone Diesel we take pride in our attention to detail which provides our customers with unparalleled repairs and service, giving you and your vehicle the attention it deserves.

Growing up in Arizona Travis developed an interest in cowboying, and was even part of the national rodeo association for almost 10 years. He rode saddle bronc, led trail rides, and worked with disabled children on a ranch where he lived and worked. One area that particularly appealed to him was the city of Tombstone and the legacy of Wyatt Earp.
