Jerome .. You are a little heavy and unfortunately the 1 ton dually weight police on this site is all they have to do. I am heavy just like you and I installed the Firestone Ride Rite airbags and it seemed like I was driving a different truck. At first, no onboard air compressor, then after looking for air, I installed the compressor. No more bottoming out. And my truck sits level. Not very expensive either. Good luck.
