Shocks might be worn out. Replace with heaviest duty shocks you can find.
Adding or upgrading to heavy duty sway bars, front and rear, with stiff polyurethane bushings will help alot, once the shocks are good.
Upgrading to heavier duty rear springs, heaviest available, will help alot too.
X-2, on the worn out shocks! I own a 04 Winnebago and I had the same problem. My RV came with Monroe Shocks off the showroom floor and they didn't last very long. I upgraded to a better shock and that cured the problem. Please note that Winnebago changes there chassis every four years. I have a 04 Winnebago on a 03 chassis so I had to buy shocks for a 03.
