Saturday I spent a couple of hours installing my Air Lift Bags. It was very straight forward and rather easy. The most difficult part was cutting off the extra threads on the "U" bolts. I have inflated them to 12 psi and will check them tonight when I get home to see if I have any leaks. I drilled holes and mounted the valve stems on the face of the hitch.
Thank you to all who contributed their ideas and comments.
