X2 on the Bison fixing the nasty bumper. I'm very interested in the zr2 if I ever downsize from the tundra. I hear high praise from a friend with the Duramax, absolutely loves that little truck. Heard from another guy the trick suspension is legit, both for higher speed and crawling applications. Before pulling the trigger I would have to be convinced that those big low hanging shocks aren't a damage risk or a crazy $$$ repair. Also, word is that AEV is coming out with an updated Bison (not through GM) with fenders allowing 35's with close to stock height. So, if (when?) I de-tundra down the road I would probably figure out a way to get Bison bumpers and fenders and set it up with 35's, and that truck would be the clear front runner for me.
