This air suspension system was great and installed easily on my 2013 F150. It took me about 2 hours to install. I currently have a tee connecting 2 bags and a line back to the bumper. I installed a schrader valve in the empty space next to the rear license plate. (The license plate light glows nicely when you need to inflate/deflate at night). I pump them up to about 33psi to balance everything out when towing my camper. I love the extra stability they add to the truck. I may add an onboard compressor later for convenience, but for now the small compressor installed in the front compartment of my RV works great. My only regret is not adding them to my truck sooner.
