I'm not entirly sure what it is, The previous owner told me it was a 1957 Chevrolet Milk Truck Converted to a motorhome, its got powerdisk brakes on the straight axle up front, hydroboost power steering, 350 on propane with 11:1 pistons, 4 speed with lockup torque converter, and a few other modifications, It runs, drives, and stops. Not entirly sure why I needed it, or what I'm going to do with it now.
