Hey Gaylan, I would recommend the Roadmaster Rear Sway Bar part # RM-1139-147 for your 2025 Winnebago Minnie Winnie that is build on a Ford E-450 chassis. This will make a HUGE difference in handling and stability for your RV and you'll definitely be happy you installed it. We have tons of customers with similar RVs as yours who have installed this bar and were very happy with it. Have you tried any other modifications to improve handling yet?

I have already installed a Hellwig front sway bar and a Safe-T-Plus steering stabilizer.

@GaylanM nice! what's interesting is that the rear sway bar upgrade normally gives the biggest improvement and usually we recommend to go that route first but doing it at any point is still a really solid upgrade.

@JamesonC - I started with the Safe T Plus steering stabilizer and when I realized you had to remove a front sway bar bracket to install the Safe T Plus steering stabilizer I decided to do the front sway bar. Does Hellwig make a rear sway bar for my vehicle and what size do you recommend? 1 1/2” or 1 5/8”? Thanks

@Gaylan Hellwig does have a rear bar available with the part # HE78RR which is 1-1/2 inch in diameter. A thicker bar is going to work to improve handling more than a thinner one but at a certain point the ride quality starts to get rougher which is why thicker isn't always better.

I have a 2024 Entegra Odyssey E-450, 31F . Installed Roadmaster front sway bar, rear sway bars, steering stabilizer, it was totally unsafe to drive at 55mph off the dealer lot, both hands and white knuckles, unbelievable. Now with upgrades mentioned 67 mph one hand on the wheel. The crap they put on from the factory is terrible. I talked with Entegra but they don't care, I'll remember that when I buy another. Good Luck!
