What is Difference Between Roadmaster Anti Sway Bars that Fit 2017 Ford Class C RV E-350

Question:

I have 2017 Ford e-350 class C RV with a stock bar anti sway bar and would like to install a rear Roadmaster anti sway bar. What is the difference between products rm1139-117 and rm1139-198 and which would better suit my needs? You also show a video of a bar that installs in addition to the stock bar. Is this something I use also? Thanks

The difference between the two Roadmaster rear bars that fit your 2017 Ford E-350 Class C RV is that the part # RM-1139-117 is the correct fit for if you do not have the auto snow chains and the part # RM-1139-198 is for the versions that do have the auto chains.
