Thanks for all the replies -
I guess right now either a F150 or F250 Ext cab 4x4 are the front runners.
There are about 50 F150's near me in my range- about a third are the extended cabs (I want and need) and are 4x4's.
I do worry about the rear axles and the lesser brakes on an 150 though......and quite a few have the 302 or the 4.6. Not too sure they will not be overstressed if I start going on longer and hillier trips towing.
F250's in the spec that I want that have not been plowed are pretty rare around here.
I may jump on the next "owned by an old man" F250 that was never plowed with a 351 4x4 that I see.
Any opinions on C6 vs. the AOD trans? I assume a few more MPG.
I had been looking at the GM Suburban/yukon, ect, but have discounted due too the lack of space for sheet goods or cordwood.
