I recenltly went round and round with the same decision looking at 35" Michelin XZLs and XZHs, and every other 35" tire on the market. In the end the MTR won again for me, and I'm planning a similar year off, round NA trip. That would be my recommendation as far as dependability, toughness, traction, cost. Afterall it is for the most part the only tire used by the U.S. Border Patrol and most Govt packaged 4x4's that go to military service or often to departments like the U.S. Forrest Service get fitted with MTRs. Or atleast on the GM 2500HD platform that I am familiar with.
