My Imperial was rated to tow 5000 lbs. That would get you a medium RV trailer but is less than the weight of a B body on a steel trailer. Andrewh hauled a 69 RR on a HEAVY home built trailer behind his 64 Dodge 880. The trip went from Idaho to DFW with a blizzard most of the way. He got stuck in a ditch once but that was due to icy downhill conditions and he had plenty of company in that ditch. The car had a receiver hitch welded to the rear rails and a load equalizing hitch was used.
