Not many rocks around your part of Texas, just dirt and mud, with some sandstone.
I am in Southeast Texas (read mud ONLY) and I ran 10 bolts for years with 36 tires without any failures, and I tried to break stuff in my youth. Of course these were non-posi front ends.
The terrain has a bunch to do with how well things hold up. If you're on solid rocks (high traction...no give)...get the 1 ton stuff. If it's woods and mud, the OEM stuff works fine. After all nothing typically breaks when everything spins free without ANY traction.
The one failure I do remember was in West Texas, after I installed a 14 bolt, posi rear end. I discovered the T-case yoke couldn't handle the added traction on rock hills....there is ALWAYS a weak link somewhere in the drive train, and rocks find it.
Much of the 4 wheel community has to deal with high traction hills, rocks, etc. and therefore everything you read is all about massive drivelines, but you don't sound like a wild man and you don't live around rocks and mountains.
For you....36's + 10 bolt OK
