My so called research shows that REO produced 220 trucks like this in 1948, possibly 20 left in existence, but if you have more substantial proof, please chime in…. Truck sheet metal is unmolested with the exception of a patch panel where gas filler neck exited , lite faux paint work there. Ford E350 motor home chassis, all ford running gear. 460FI engine, auto tranny rebuilt, new tires ,new wiring, new glass, new flat bed, custom exhaust, tuner, rebuilt original speedo cluster, needs some finishing, but street legal now . Amazing head turner, plus a beast of a hauler…call is best, Ray@970-309-4526. Truck resides in CO. Thanks for looking !
