I bought a new camper that weighs 4,000 LBS. I put new shocks, air bags, steering stabilizer, and sway bars front and back. Don't let anyone tell you it is easy to install on a 2015 Ford F250. Had to lower the gas tank and us long extentlons to get to the drivers' side bolt. The bolt was a bear to remove because it is in a rubber bushing. When installed it works great. The truck is much more stable even with the camper on. Would do it again.
Not so easy for toyota or nissan
2007 Titan. It is about ten times the work than the video shows. A couple things that I did not like. The kit comes with new longer center bolt (to stack higher). The original is non-removable. The back side of the springs go right over the existing roller. Once you tighten down the u-bults it renders the roller useless. Not sure how wise that is? I would go with a kit that fits this vehicle better.
