I have a 2000 F350 Crewcab 7.3 liter powerstroke 4x4 longbed single rear wheel. I carried a Lance camper that has a 11’3” floor. I switched to Vision 19.5” wheels, on the wheels I have Toyo M920, 245/ 70R – 19.5” tires. The wheels are rated 4500 lb’s & the tires are rated 4540 lb’s. I now have a lot more safety margin compared to the stock 16” wheel and tire combo. The stiff side walls of the tire made a difference in reducing the sway with the camper on board. It is nice to not have the tires squat when loaded. I don’t have a need to air down so that is a non issue for me. I don’t know when I can upgrade to a dually. So I did research the 19.5” tire subject for several years before making the change. It is a expensive up grade. I am happy with the results I have gotten since going with the 19.5” setup.
