Model Overview

The Signature is Truman's flagship build — a full-size Ford F-450 engineered to be the only truck you'll ever need. It starts with a super single rear wheel conversion that puts wide, military-grade single tires on all four corners, dramatically improving off-road traction and ride quality while maintaining serious towing capability.  Add LiquidSpring active suspension and the Signature handles a loaded camper on a fire road the same way it handles an empty highway — composed, controlled, and confident.

Starting at $175,000 including chassis. Final price depends on trim level, package selection, and accessories.
