I had a 1500 Silverado Max Tow, that towed a 36’ TT that had squatting issues also, the weight distribution was 1500# weighted, my tongue weight was 1200#. I did not want airbags cause I heard stories that you always had to check and make sure you had the correct air pressure for the best ride, so I invested in Sumo Springs, you can purchase these from ETrailer.com, they take the the place of your factory bump stops. I noticed better control, reduced sway, very little squatting, I was not impressed with the Timbrens, to stiff, I wanted to maintain that smooth ride, the Sumo Springs only got stiffer the more weight you applied to them. I also took off the factory Hitch, which was only a class 3 and replaced it with a class 5, wow what a difference, you can also get that from ETrailer, their very helpful and they also show you videos on the products they sell.
