I just went and checked the bolts on my 2" RRO body lift the other day. I couldn't get any of them any tighter than they already were. It's been a little over 2 years now since I first installed it, and haven't had a problem, with the exception of the silly little mounts that are supposed to support the frame/body up near the rear coil spring mount. Those didn't hold in very well.
When Fletcher first said he was busting mounts and that, i figured he lived on the east coast with bad rust situations, but then i saw his profile, and he's in utah. I personally haven't ever seen frame or body mount problems on a tracker/sidekick, other than those really rusty ones from canada and the east coast.
I do agree that I wouldn't do a body lift, unless i had to, and on my vehicle, i felt it was pretty much a requirement. The gaps are horrible though.
