Overhaul and Upfit Services

The Grigsby Truck Difference

The true art of reconditioning and modernizing vehicles includes a touch of handmade elegance not found in modern manufacturing. Grigsby Truck Company is unique among others who offer similar services because we combine this art and vision with attention to detail that can only come from a background in meticulous aviation maintenance practices. We’ll help you preserve an incredible vehicle while adding just the right twist of modern performance, rugged luxury and impeccable craftsmanship.

Build Your Own

We specialize in FMTV Chassis, and are pioneering many of the upgrades and modifications that make them more enjoyable and reliable for civil use. We pride ourselves on attention to detail and thoroughness, and understand that the Army deploys MTV and LMTV trucks with many backup vehicles and a regiment of support; we realize that you will not embark on your adventures with these resources. Therefore, we take measures to ensure details affecting reliability are given full attention– offering custom level overhauls, plus optional upgrades, upfits and modifications based on client and vehicle individual needs.

Due to high demand, we have a waitlist for our services. Please email if you want to request a spot on our build-project waitlist.
