I ultimately went with Michelin LTX MS-2 and have been happy.

I'm getting new tires on Sunday. I really like the Michelin m/s 2 (70k warranty) a lot for all highway driving and had them on my previous truck. I got great wear out of them. Prior to those I had the Michelin At/2 (60k warranty) Another good tire, but not as good of wear. In both cases those tires cost over 1k installed. On Sunday I am going to have Cooper AT3 (55k warranty) tires installed on my 2500hd. The reason I am trying the Coopers is Bob Summeral Tire has a buy 2 get 2 deal this weekend. So I'm getting them installed out the door for 1/2 the price of the Michelins and only losing 5k in warranty. I'd be fine with a more highway tire, but the AT don't bother me either as I occasionally take the truck to the farm.
If I wasn't getting the Coopers I would get either the Michelins or the Firestone Transforce.
