I might be able to trade my minivan for an old motorhome. It has a 454/TH400/D70 rear. Its kinda ratty but I think it would make a good tow rig. I believe its 35 feet? Any way I might be buying an 18' trailer and would haul it with the motorhome. Would this require a CDL? Any one have good luck towing with a big old motorhome?
