Hello, I am new to this site and just wanted to say hello and tell you that adding a auto leveling system to your rig is the best thing you can do. I had back surgery in Florida while visiting my mother and as always I spend too much money there and bought a new used 2013 Bighorn without the levelers. On the way home I stopped in Mesa, AZ and had the Lippert levelers installed and what a big difference it has made, no blocks or bending down to make the rig level, just one button leveling!
