I have a 13' crew. Added a 2.5" lift for rock clearance and then added Kevlar tires because of mesquites. I have only had 2 issues.
1. Because of my probox top, it has made it top heavy. Be very careful and do NOT "powerslide". It will tip over!!
2. The back rubber bushings on the torque bar squeaks. I just spray wd-40 on the them and it's good to go for a week or so.
