Lol my 2007 sprinter was 2wd and I think the only time I got stuck was on a farmers side road....and after 7 years in that van and 2 years my ford cargomax. I think I would go after a gas transit as my next van if the cubes are out soon.
If it's on the very edge of the rim you can take a adjustable wrench and slowly bend it back to a round shape. But it's going to be better to buy a new rim if it takes another hit there.

1. bed with 3 skid
