Also, check your tire pressures. I think the MH handles better with more air in the rear tires. I run 80 psi in the rears, 70 PSI in the fronts. When I got the MH the dealer had set the inner rears to 65 PSI, the outer rears to 80 PSI, and the fronts to 70 PSI. I think he intended to set all the rears to 80, but had a valve stem extension issue and just filled the valve extensions on the inners to 80 PSI - see this thread: http://www.forestriverforums.com/for...ure-45973.html
Also, you may have to slow down - especially in strong cross-winds. On my 2012, I have gotten dash warning lights in strong cross-winds that only reset when shutting down and restarting the engine. Some sort of Mercedes stability control system.
Finally, after my OEM tires wore down (about 35K miles), I replaced with Michelins. I think the Michelins have improved handling quite a bit.
