All, I had the same problem with my 2002 Monaco Knight. What I found out was my ride height adjustment was off and that the tires ( Michelin X2’s ) actually should only be running 88 psi in the front and 85psi in the back after I went and got each axle weight tested) in lieu of the 100psi it said in the manual. The difference was night and day. I made a 100 day trip across the US and could not believe the difference!!!!!!
