I know you are not supposed to flat tow. I have exhausted all searches on this and I know its a no no. I currently have a motorhome that I flat tow my Silverado with. I don't want to haul around a trailer with my van (40' motorhome and would need a 25'+ trailer would be a pain). Does anyone know of a dolly system that would lift all 4 tires off the ground for long distances?
