" I have done everything except adding the trac bar" The trac bar and or sway bar is what helps the problem you are speaking to. I had a terrible problem with mine ine the wind. I opted to put a Helwig rear anti sway. This really cured the problem I suppose a Trac bar would also tame it down. My problem was sway on quartering winds so I put the sway bar on. I also added the safety steer and the CHF. I am quite pleased now with the performance. My coach has a heavier Chasis and a longer 228" wheel base. If you have had you have had it I hope you don't lose your shirt on getting rid of it.
