well thank you sandia man , im being very open minded here, i have spoken to many people whom are friends and on facebook , they all pretty much experinced the same issue as i , they made the addition of a rear track bar , and it was another vehicle and having alot less stress,it was like driving in a tornado before the rear track bar installation afterwards, smooth as silk , i have heard this from many rv owners , not just on winnebagos , due to ford makes a cookie cutter chassis , one size fits all , they build them as cheaply as possible , and the motorhome coach builder wont add it on since they are NOT building the chassis, just the motorhome , to me its a safety issue , no less , and im headstrong about this , funny how sao many people have experienced the same issue, and some have not ,
