I had the same problem with our new truck. I only had 4 1/2 inches. I called Lippert and they said it was made to lower the pin box. The dealer lowered it for me and now I have about 5 1/2 inches. And of course I can vary this a little with my air bags with the onboard compressor. IMHO, I think 5 inches should be the lowest anyone should have.
