Why put A/T tires on a DRW truck? You are not going to do any serious trail running and a highway tread will provide much longer tread life. I would go with the Michelin's, all of their LT models provide exceptional tread life.
My neighbor is about to change out the ones on his truck after 60,000 miles and he never rotated them the entire time and they still have usable tread. He is not going with Michelin tires though as they pick up gravel and fling it up at the sides of the truck and he spends a lot of time on gravel roads at his dairy farm.
