Thanks for the comments. I have learned a lot. After watching this video, I ordered the Sulastic kit. I also spoke with a local Truck/4x4 speciality shop with an excellent reputation. They said they had excellent results with the Sulastic Kit. They also suggested Rancho 9000XL shocks. They also suggested airing down and loading the bed with some weight. I think that I am going to do all of the above.
Links below. I have no connections with any company, just trying to set up my new truck for the next 10 years, with camper on sometimes, and camper off most of the time.
