Excellent advice from "j-d". I only ride with 65 PSI in the front tires but 80 PSI in the rear tires due to the actual weight carried on each axle. With the long overhang on most Class C motorhomes, it's easy to have too much weight behind the rear axle and that weight acts to lighten the weight on the front axle which can cause poor handling. I moved almost 100 lbs of "stuff" from the rear compartments to storage further forward after weighing my rig the 1st time after it had been fully loaded. Having the correct distribution of weight and the correct tire pressures makes a BIG difference in the handling.
