One shop, multiple platforms
From basic service to complete builds.
Bring us the vehicle you own and the work it needs today. A project does not have to begin as a restoration.
Dietrick & Wilson Overland works across the full ownership cycle: inspections and routine maintenance, mechanical and electrical repair, restoration, fabrication, system integration, and complete overland builds.
We respect what makes each platform distinct. Parts availability, original design, past modifications, road manners, and intended mission all affect how work should be planned.
Other military and specialty 4x4 platforms may be considered after an initial conversation and vehicle review.
