Headhunter is correct about 4 corner weight vs tire pressure. Our 2019 32SA came with over a 100 psi all around. Now running 88 psi all around and it also came with Sumo,s. Improved ride, but still rolled, swayed, porpoises and beat you to death on the hiway. We ended up replacing shocks, sway bars, adding rear trac bar and saf-t-steer. Totally different vehicle. Cost about half of what Liquid Springs run.
