Hey Joel, we do have Roadmaster sway bars that fit the front and rear of your 2017 E-450 Class C Minnie Winnie with the part # RM-1139-189 for the front bar or part # RM-1139-147 for the rear. Hows the handling currently?

Buy rear sway bar stopped by RV rear moving around. It feels like a van now not an RV so I recommend a sway bar for your rear sway bar. PS it stopped driving like a tank now. It drives like a van.

Installed on my Thor outlaw, 34 foot on a 450 Ford Econoline base. I got them because driving the Thor was like driving a beast way too much motion and constant adjustments of the steering wheel. I placed on this sway bars as well as stiffer Beilstein shocks. Huge improvement overall. Still does not match the drive of my diesel pusher I got rid of years ago, but definitely an improvement in driving and I would recommend.

I have a 2019 E450 Minnie Winnie and installed the same sway bars. It makes a noticeable difference when you have strong crosswinds or semi trucks passing you.

I had to drill two holes for the installation and when I was done the body sway was reduced by 90 to 95 per cent. Most of the push from semi trucks passing and meeting has been eliminated. The handling, yes I know it is a big box, was improved immensely. Still have the side wind push to a limited extent but greatly reduced. This upgrade was the last one I did. The first was the front sway bar then the rear. The rear made the greatest difference.
