Boyertown Aluminum body on F350 4x4

Professionally built for Colorado River Runners, located in Flagstaff, Arizona. I purchased 30 ago to use in my business. Never really did what I wanted to do. Engine is rebuilt by 4 star and flat purrs. I replaced exhaust manifold with new one. Fixed oil leak from valve cover in which I removed and engine has absolutely no slug what so ever, clean as it can be. Had radiator gone through rodded and pressure checked. All new brake hardware in rear replaced drum with new, new bearings, races and seals and fluid.. Also one new drum and lugs. Four wheel drive works very well. You can put this unit in granny lo, let engine idle and can climb surprisingly well with out touching throttle. Only one in the world to my Knowledge. Work van, food truck, beer wagon, or RV? Swat truck? Any questions,, don't hesitate. Thanks, for looking!
