I have a 2017 Winnebago Vista 29 VE 18,000 GVRW and experience significant (to me) rocking on uneven roads. The local dealer recommends replacing the stock sway bar with a Road Master (RM-1139-0146) anti sway bar. He said most people only get the rear and like the improvement. First, all I have read states to leave the stock bar on and add the Road Master, does that make sense? Secondly, does only adding the rear make a enough of difference? I don?t want to spend more money but I also don?t want to move forward only to find I need to do more. Thanks!
