I purchased a 2013 Thor Windsport 32A on a F53 ford chassis and it rides like a tank on any road other than a smooth top road---any suggestion as how to correct rough ride?
Look, at the label, besides the Driver's position, or the door jam and adjust tire pressure to that, not maximum pressure, on sidewall. If that doesn't do it, maybe you have too stiff, a tire, sidewall. Some run semi tires, stiff enough, for 50 tons. An RV spec tire will generally have more flexible sidewalls. Look at shocks, are they gas? Gas units are stiffer. Is the coach loaded yet? The weight affects it.
