Since the other day I saw three inch tubular bumperes installed on a vanagon in the rear.. with the original carat bumper still installed up front... and this combo looked good...

Its made me wonder if this wouldn't also be good for enhancing snow traction since some people have said they try to weight down the back of their van with sand bags when it snows...

then too... with a hitch as part of the bumper you could install a rear cargo box that attaches to the hitch and weight it down with tools or sandbags...
