i have a bagged crewcab dually chevy squarebody, and a 42' 3 axle 5th wheel project...its also bagged

i have this "thing" with being able to roll up and drop the truck/trailer flat on the ground.
eventually i wanna build a "toterhome" style hauler out of a 40's vintage COE, use a duramax/alison, haul 1 car or a couple bikes with sleeping qtrs.
