It likely has a gas engine, 5.7 liter with a turbo 400 trans. (3 speed).
Assuming it starts, stops, runs good and shifts through the gears including reverse. Assuming it is still located in Colorado. If not, where is it now?
While most will not care, but the wheelchair lift needs exactly what to function?
The interior has a Spartan look, so assuming a corresponding asking price?
Good luck in your sale...
