X2 on Hondarider 552 reply. Your truck weight is probably about 7500 lbs with a fifth wheel hitch in it and a full tank of fuel.
Just to give you information on rear drop - my 2011 3500HD SRW drops about 2 inches with the air bags initially at 8 lbs. I put 50 lbs in the bags to recover most of the drop. The air bags are easy to install and they will improve the ride too. I installed Air Lift 5000 on mine. I took my truck to a local transfer station and the weight is about 8000 lbs with the fifth wheel hitch in it and a full tank of fuel.
My additions; Bed Rug bed liner, Luverne SS running boards, Air Lift air bags, Handy fifth wheel tail gate, GM rear wheel liners, GM rear seat storage tray.
