I had two astro vans, one an 89 rwd with the GM factory Eaton locker, found it to work just fine in the WET snow we get here in the nw. That was traded on a 2000 AWD, with bridgstone winter duellers, it was dang near unstoppable in snow around here!
With this in mind, IF you can find a GM van with the G80 locking rear, get some GOOD DECENT snow tires for the snow you drive in, a van should do reasonably well. Not as good as something with all 4 driving per say, but reasonably well. Bad tires and you do not go any where, even if you do have awd or 4wd, ala put 4 michelin XPS ribs, and plan to drive in the snow! NOT!
As far as drive train. for the GM as I know them better than Fords, the 6.0 gas if you can find one with the 6 sp auto, at least 3.42 gears, better would be 3.73, you will do fine pulling. If you find a 4 sp auto, 3.73 min better is a 4.10 with that auto! The reason is the 4 sp auto has a first gear of 2.48 or effective about 4-1 in first, the 6 sp has a 4.10 first, effective about 6.5-1 with the tc engaged. So you have have a LOT higher axel ratio with the 6 sp, and still have a lower overall low to get you moving etc! This is a number a LOT of people do not pay any attention too, and they SHOULD! BIG TIME SHOULD! The ratio's int he tranny can be more important comparing vehicles than the pumkin axel ratio!
