I run Falken AT3 Wildpeaks on my company truck. We have a reciprocal arrangement with them so it's on all our trucks. I've run the M/T in the past. In my experience on the Superduty, I'm getting long life out of the AT3's with rotations around the 5-7000 mile mark. With weight in the back, they are unstoppable in the snow. However, with no weight in the bed they are just ok. Made in Thailand I believe.
