I ran some Toyo Open Country AT's a few years back on a Chevy 1500 I owned. Pricey tires, but I had a buddy that worked at the tire dealer and got a really good deal. I really liked the tires, but they wore very fast (25k miles +/- as I recall). For me, they weren't worth the premium price they typically demand and not something I'd go for again.
This is the first set of BFG's I've ran in a really long time. Last time was a Corvette and that was many moons ago. A different type of tire altogether and the experience was just so-so at the time, although the tire demanded a premium dollar. Based on that I was a little leery to dump the cash on BFG's but the reviews on the KO2's really are great. Lots of guys getting 60-80k on a set. Plus as I already mentioned, it was the look I wanted and gave me traction for a variety of obstacles.
Here are a few pics of them on my truck:
