BFG AT's are good in everything but mud. If you get into the mud you'll have to keep on the skinny pedal a fair amount to keep them clean. If you can look past the mud performance, they do great in everything else...sand, snow, rain etc. I got about 55K out of mine and they still had probably another 5 or 10K left in them. They do get hard to balance when they get old though. I had a minor wobble that was a result of them, as does a friend of mine running the AT's on his XJ.
In other news, I spent yesterday combining my belongings from my parents house and from a friends house into my new apartment. Woke up at 6:30 to start moving and didn't stop until shortly after 11:00 last night.
Pulling a uhaul trailer behind the Jeep pretty much destroyed what little MPG's I get.
