I have the on a F250SD with 100,000+ towing, a couple different 5r's, and it levels ride and stops bounce. I'm pulling a 10K TT now and carry 50psi in the bags, I have not had to adjust this year. I have the double valves just above the bumper. I check PSI on the bags, TV tires, and TT tires before each tow.
