Propane runs great olds engine . The paint isn't perfect , there is rust under the box liner and underneath. . I believe this truck use to be a diesel and Some one put an olds 355 in it on propane. Propane costs under a dollar . It has a fuel gauge that works however it bounces around but works when still. The interior is blue and brown. I have put new brake callipers on the front and a new portioning valve.
