That's a very valuable 2 cents.
Question though would the gas mileage difference be a deal killer?
I know the cube vans get about 10(dual rear wheel) I have no experience with the smaller single rear wheel, while a van gets 16 or so.
I've seen the DOT in Indiana and Ohio at rest stops checking trucks too, not sure if they pulled the truck in there or just stopped to check the trucks parked there
