OP, let me guess, even with your listed highway percentages, I'd bet you do a fair amount of driving into the mountains and back? Plain and simple fact is that mountainous driving is much harder on tires, expect shorter tire life. Add in the weight of these trucks on mountainous roads...
I do live in the mountains, just west of Denver, and have experienced the same short tire life. The OEM Michelin tires only lasted 22k miles. Went with another tire after, forget the name, but again, about 23k miles. I'm currently running Goodyear Wrangler Duratac now with about 25k miles and still looking good. I suspect I might get 40k miles out of them. My priorities were around load range E with decent traction on snow.
