this is something i have always imagined. try to picture this. have a vehicle similar to a NPR(or a 1 ton pick up) with a flat bed that goes inside of the rear wheels. kind of like a cross between a truck and a open trailer. the truck could even be front wheel drive. the bed would be the same height as a standard open trailer. the bed could be about 11' or long enough to fit a 36" a 48" walk behind and a rider on. could build a little multi level system and have the 36" above the deck of the walkbehind. no need to ever pull a trailer and it would be nice and close to the ground. what do you think? would something like this ever be possible?
