Thanks for all the replies. They give me a lot to consider. When I put the camper on the first time, I put 50 psi in the airbags "just because." When the truck did a bunch of rolling, I increased the pressure. Maybe I should have decreased instead.
This rig is so new to me that I need to do some serious investigation into the matter. If there is a factory sway bar, perhaps it needs new bushings. I don't know how much the truck will squat if I put the minimum air in the airbags. So, I will take all your advice into consideration. I also look forward to hearing froum flipskid about how adding new bump stops works. Again, thank you all for your input. I'll report back when I know more!
