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.
