Vehicle Reconditioning

GTC is a custom automotive shop specializing in overhaul of vintage utility-type vehicles such as trucks, wagons, vans and military surplus trucks. Our focus is on full chassis recondition per client specifications.

Our team possesses unique knowledge, experience and love for this business. We’ve put our family name out there with intention—to share our passion for building vehicles that are durable, innovative and up to the highest standards. Our work speaks for itself, but we value a collaborative approach. Each truck is a personal extension of you—our valued client. Your influence, inspiration and intended purpose drives what we build. Whether we work based on recommended build specifications or begin with a clean slate, our team will steer you towards a unique vision, your gateway to adventure.

The wait list for a build is currently at (2) two months. Great things come to those who wait, and each job takes many hours of detail-oriented work.  Right now, we limit the number of custom vehicle projects in the shop at a time. As we continue to grow our staff and resources, so will our production capacity.

To get started, we require a 50% down payment on the estimate. As the project moves along, we will bill you for two 25% payments of the actual cost. Your initial deposit secures a slot in our production line.

Each GTC-built vehicle is delivered with a one-year, limited, bumper-to-bumper warranty.  After that, you can count on our lifetime after-sale support services to help you whenever an issue arises. No matter the situation, we will work with you to find resolution.

Our team will research and assist in finding the best third-party service point at a convenient distance from you or along your travel route.

Our supply chain, tooling and reconditioning process includes Stewart & Stevenson (1996 – 2006) Family of Medium Tactical Vehicles (FMTV) U.S. Army military surplus truck. This includes (4) four chassis variants of the 4×4, 2.5 ton, Light Medium Tactical Vehicle (LMTV) and (13) thirteen 6×6, 5 ton, Medium Tactical Vehicle (MTV) variants

The FMTV is based on the Austrian Steyr 12M18 (4×4) truck and was modified to meet U.S. Army requirements. The original prototypes were assembled in Austria and fitted with a number of U.S. supplied components such as a Caterpillar 3116 diesel engine, Allison automatic transmission and Meritor drive axles. You can even find Steyr badging on some components of the truck, such as the steering wheel and windshield washer fluid reservoir. Additionally, most measurements on the truck are metric and the Cab Over Engine (COE) design was unique amongst American military trucks, making it on average, 3 feet shorter than the predecessor 900 series of military trucks. The truck-making division of Steyr was taken over by MAN in 1993 and the Steyr medium tactical truck was phased out of production in the late 1990s in favor of MAN designs, with Steyr discontinued in 2005.

Caterpillar 3116, Caterpillar 3126 and Caterpillar C7 are the (3) three stock engines in FMTV surplus vehicles. The tuning and emissions controls vary among the differing models.

Yes, many of our customers are very interested in all aspects of overlanding—an activity that continues to grow in popularity. Some are true modern-day overlanders—traveling for weeks over long distances where they camp, hike, sleep and sustain themselves with limited supplies.  Many are weekend adventurers who take their specialize vehicles to an interesting location to stay for a few days of outdoor fun and exploration. We’ve worked with a few urban overlanders too—people who make a road-trip of seeing various places without leaving the pavement.  And there are those who simply love the style of trucks used to take these big overland trips and that’s ok, too.  We are here to help make your ideas come to life—for however you live, work and play.

The CAT 3116 engines in these trucks are an entirely mechanical motor with a MUI (mechanical unit injection) fuel system, and the CAT 3126 engines use a HUEI (hydraulic electric unit injection) fuel system and ECM (computer) to operate the fuel system. The newer C7 engine also uses this system and has additional emissions controls. In the CAT 3126 and CAT C7, the fuel injection system fails more frequently but is easier to repair than the all-mechanical 3116 engine. If your injectors need replacing on the 3116 it is a more extensive replacement process, but it is going to happen less-frequent because this engine configuration is less sensitive to poor fuel quality. Either way, these old CAT engines are in boats, buses, and tractors all over the world, and finding parts and service shops is a manageable task. The community of enthusiasts around these trucks are split on 3116 vs 3126 if they plan to venture into regions with unreliable fuel quality.

GTC is located in Bend, Oregon on the eastern edge of the Cascade Mountain Range. Known as a prime spot for year-round outdoor sports, Central Oregon is a place to enjoy mountain biking, hiking, fishing, golf, hunting, camping, sport shooting, off highway vehicle exploration, rock climbing, white-water rafting, and numerous winter board, ski and skate activities. The closest commercial airport is Roberts Field (RDM) in Redmond, Oregon.
