Swaying in the Wind

So what seems to be the general solution to cure some of the wind swaying on the 3170 sized motorhomes? I'll admit a 30+ mph side wind I fully expect some swaying but WOW, is this thing a handful.

It drives exactly like a sailboat with too small of a rudder. Right, Left, right, left.....

I've followed all the tips on here about tire pressures and air bags etc but really nothing helps at all.

Do most of you upgrade the front stabilizer or add the TruCenter to the front?

I have a 3171 forester and I have not had any wind issues. I didn't do anything to the motorhome except fill up the airbags. When a truck passes me I can feel it, wind might make the RV sway a bit but nothing I have been uncomfortable with so far. Maybe I'm just lucky. I had a 30 foot toy hauler previously and have not noticed anything different in the wind compared to that.

I guess the issue is I don't have anything to compare it to so maybe white knuckle rides are the normal thing with class C motorhomes.
I've driven school buses and dump trucks but they were nothing like this. Must be the heavier duty chassis on those vehicles improved the ride.

I will say that I'm betting as much sway is there is on my particular MH that tire wear must be super high. I feel like I'm a race driver scrubbing the tires before a re-start.

I also fund that the driving experience was a handful in windy conditions or with semis-truck passing. I installed a SAFE-T-PLUS (http://www.safe-t-plus.com) steering stabilizer and it improved my driving experience incredibly. I strongly recommend it.

We had our new Forester 2651 out this past weekend. We drove 70-80 miles with 35+mph cross winds. It was not fun but this was my first experience driving a motor home. I didn't feel in any danger but was extremely tired at the end of the day! My air bags were at 70psi for a lightly loaded unit. I slowed it down and it was better but still a challenge.

After some reading I think we'll give the Safe T Plus stabilizer a try as well and see how that works.
It's not too costly of an investment and I can't see any reason why it wouldn't help, something has to.

My shoulders and neck are still sore from yesterday's 160 mile drive.

I talked to someone at a rest stop yesterday who was driving a 40' diesel pusher and they were having issues with the wind too. I could deal with some wind but clenching up every time a truck passes us is more than I can deal with.

It is a complete different animal than when I had our Dually and 39' fiver then driving the motorhome. learned that slowing down to 65 made a big difference. Cant speak for the class "C" MH. Its a balancing act in getting tire pressure, load and driving looking further forward than normal. Any strong side winds will make for a hard day driving. Goodluck and safe travels.

Are you sure it's not caused by the front end alignment? Do you have any heavy steering or bump steer on undulating road surfaces? It should handle and feel pretty much like a car. For my coach correct alignment made a world of difference. Wind causes the coach to lean which yields the same result from the front end geometry as uneven road surfaces. Search the forum for alignment specs that Brian posted which seem to work well for people.

Swaying

I had the same issue, installed a Roadmaster steering stabilizer and got the front end aligned, it was amazing how much difference it made. Good luck.

Had the same issue. Load the motorhome as if you are taking a trip. Even some water. Air bags to 70 psi. Tire pressure correct based on the door sticker not the tires. Then drive to a local alignment shop that specializes in medium duty trucks and get an alignment. Mine drives like a car now!
