Class A Wind Handling

We just upgraded our 27' class C to a 2016 35' class A Winnebago Sunstar LX. My biggest trepidation in the upgrade is how it will handle in the wind. I have read several things about gas class A coaches being much better than they used to be, and some have said Winnebago is generally on the better end, but I'm wondering if anyone has had experience with this particular model or something similar. Am I going to be spending more time waiting out the wind storms, or will it be pretty reliable? Should I consider adding sway bars to the axles (I might be using the wrong terms here, but I have heard you can add some stability that way.) I'd love any other tips or input anyone might have.

  • This is all great information. Thanks to everyone for your input. I'm going to look into all of these.
  • Long post but I've pretty much have run out of stuff I can bolt to the chassis. In order based on what I thought returned the best bang for the buck-

    Cheap Handling Fix (aka CHF) - Very long posting on IRV2.com. Basically changing the dynamics of the Ford installed sway bars to increase body sway resistance. IRV2 CHF Thread. My cost $0

    Tire pressure - Either use the builder's placard listed pressures or get the coach weight checked with you normal loading (including people) and set the tire pressure per the tire OEM charts. I noticed at around 10 or 15 PSI high for cold pressure I could not keep the coach in lane. My cost $10 at a Cat Scale.

    Koni Shocks - Was a bit hard on the coach budget (about $150 each) but ended up being a nice ride improvement over original. My cost around $450.

    Panhard bar, track bar, or track rod - CHF reduced but did not eliminate tail push caused by cross winds or passing vehicles but once I added a track bar I've been surprised by 18 wheelers that suddenly appeared at my left elbow. My cost $600.

    For wind handling I would not go much further. I have other add ons (air bags, steering stabilizer) but for the most part the what I listed had the most dramatic effect to counter wind.

    Was out when the a edge of Hurricane Sandy passed by. Constant 30 to 40 MPH cross winds but the coach movement was very manageable

    Almost forgot, the coach is build on a 2006 18K lbs GVWR F53. Normal load weight is around 17,250 and I tow a 2005 Honda CRV which weighs around 3500 lbs. Your results will naturally very.
  • I also installed the air bags in all four corners with a dash control to inflate or deflate them. When traveling in the Great Plains when it was windy I would just increase the air to provide a stable ride. Once the wind passed, I could deflate them for a smoother ride. Anti-sway bars stiffen the ride at all times, which I did not want.
  • The last two MH i have purchased we 33 then 36ft. For both I installed air bags on the rear axles. If you look underneath at the rear axle. you can see the totally inadequate springs. the air bags help stiffen the (box) to the frame. Sure worked for me. Was driving across the Mojove desert last year, wind was so bad a semi blew over. Trucks pulled over at every on ramp. We just motored on, all be it a little slowe,r but felt safe. Bought them on line at SD Tucks I think it was.
  • I am quite happy with my '03 F53 chassis handling in wind. I have had only a few situations where I have had to pull off the road in a rest area or campground because of the wind. These rest areas usually fill up quickly with all types of large vehicles in high wind conditions. Of course, a side wind is the worst. However, the coach is manageable, but becomes tiring fighting them. I'm sure your '16 will handle better than my '03. Before you begin adding suspension parts unnecessarily, I would see how it handles stock. Other than shocks, I have not added any suspension parts.
  • It's a box...physics can not be overcome. At some point you will be uncomfortable, find that point and know when to pull over.
