This beast of a toter home hauled my 36' bumper pull race trailer with tools and two cars with a lift inside with ease! It has a Cummins 500 diesel engine and a 13 speed Eaton Fuller transmission that was just rebuilt. It was the only thing needed when I purchased it 6 years ago. I haven't been going to races with two cars the last few years, so it's time to downgrade to a dually and a single car trailer.Engine - Cummins 500Trans - Eaton Fuller 13 speed36' long26.5' box3.5' attic for storageInside could use refreshed or even redesigned if a guy wanted to convert the back to haul a quad or golf cart and there is living space in front of that with a bathroom and kitchenette and couch that could be a pull out bed as well, or keep the bedroom in the rear.
