The Goodyear MT's are supposed to be good, but very expensive. I agree with Motorhead 426's comments mostly.
The BFG AT's are very good all around tires, but the tread picks up and holds alot of rocks and acorns, which bugs the heck out of me. I think the BFG MT's are better in snow though.
The Firestone Destination MT's are awesome, I just switched my other truck to them, but they only are available in limited sizes.

Agreed with the last post on the Goodyears.. You have to pay an arm and leg for a decent Goodyear tire. I replaced my Goodyears with Toyo Open Country AT's 285/70's and they haven't let me down yet.. and the price was awesome as well.
