BFG KOs have always been my go to for a quieter ride with good off road capabilities. Generally I get 60k out of a set...at least the 3 sets on 3 trucks I used to have. My brother swears by the Grapplers...he runs em on a 3/4 ton Dodge and claims he's done 40k and they haven't lost half their tread depth yet. On my daily (Accord) I just swapped to my 2nd set of michelins(defenders)...first set got me 80k. I'm pretty sold on the cost of Michelin tires being worth their long term performance...but I've never ran them on a truck.
