I agree with all the others Rhino Line the floor, install some paneling on the wall, Get that Baxley bolted to the floor, make a mount on the wall to bolt up your new ramp, and get all ther other stuff bolted down so it does not slide in to your bike. Try to mod the van so you can bring power to the back via like a generator so you can plug in small things like a heater, or tire warmers, run a small air compressor you know stuff like that and that van will be a good bike hauler.
