Cool project. Seen that done with old school busses, the motor home chassis will be cooler yet. What power plant/drive train does it have?
Naturally, that old Concord looks very familiar. What year model is it? In 1973, I bought a new 18' Winnebago Brave that had a 318 cu. in. Dodge Industrial engine, and of course 3 speed automatic with the shift lever in the dash.
