Grigg,
Just to add to the discussion ... why does it (the hauler) have to be 4x4? You know my hauler ('95 Cummins Dodge 3500 dually) and with more than 60,000 miles now, I can't think of a single time when I needed/wanted the 4x4 capability with that truck. I see all these 4x4 duallies/haulers around and wonder where they go that they need 4-wheel drive?
Granted, some people have a need for it, or a desire. And I'm not dissing anyone. I'm just curious.

John
