Weighed my coach prior to a 1000 mile trip and adjusted my air pressure to 5 psi above the Michelin chart. What a difference, smother ride wander almost non existent and when trucks pass no movement. This is on a stock 2006 F 53 chassis front Track Bar with front and rear Sway Bars. Best 6.00 dollars I ever spent to have it weighed. This is my fourth motorhome and never weighed any of them before this. I would suggest that if you are having handling problems to have your coach weighed and adjust air pressure accordingly.
