Hi. I have just bought a 1987 Chevy G20 Horizon RV/Camper. Seems to run ok and been in the garage this morning for a look over, a few drips and some minor rust but other than that not too shabby. The mechanic said that the tires weren't the best for the job of an RV (although he did say they were good tires and brand new). The Van does sway a little and roll on the corners (think I may have to upgrade the Shocks too as these were changed by the previous owner and are a little soft). What tires would you all recommend? Current tires are P235/75 R 15 105T. I'm new to the RV world so any help is good.
