Question:

Im looking at adding a rear sway bar to my 2017 Winnebago Vista 31BE. What is the difference between RM-1139-145 and RM-1139-146? Both seem to say they fit.

Roadmaster rear anti-sway bar # RM-1139-146 will fit models with a gross vehicle weight rating of 15,700, 16,000, or 18,000 lbs. It fits coaches which are less than 34 feet long. It does not fit the Thor Outlaw which isn't a factor since you have a Winnebago.

Bar # RM-1139-145 fits models with a gross vehicle weight rating of 20,500 pounds but does not fit the Thor Outlaw. Also this model fits only if the shock mounts are parallel to the ground and have two holes.

I checked with Winnebago and your 2017 Vista 31BE has a gross vehicle weight rating of 18,000 pounds so that means that # RM-1139-146 is the one for you. I have linked a video showing an example installation for you.
