Re: Express Van with Quigley 4x4 or AWD
If I wasn't going to do any true off roading or go anywhere that additional clearance was required I would hands down opt for the AWD system. No hubs to lock in, no transfer case to engage, no drivetrain binding when in between patches of snow/ice/etc. I would guess that you would get better MPG with the 1500 too simply by being lower to the ground all other things considered equal. Check the tow rating and payload of the 1500, but I'll bet it would take care of what you need.
FWIW, I don't have any personal experience with the AWD van, but drive a Chevy 1500 pickup that has an AWD mode as part of its 4x4 system and it is so nice for driving around town without having things bind up as they would when in true 4wd.
