Wander and Sway

We have a 2014 Sunseeker 3010DS. What can we do to eliminate the wander/sway we get whenever anything from a Smart Car to a Tracker Trailer goes by us?

The first thing is to check that your tires are properly inflated. Then put about 60 pounds in the airbags. That's the easiest to do and makes a difference. The next step is to get it aligned to the tighter than Ford specs that you can find on this forum. We have a 2015 3010ds and after doing that it handles very well. There are other things you can try but these give the most bang for the buck.

I will have to say the best thing I've done is add the Henderson rear trac bar for what you are talking about. Our last trip was the first time I had it on our 3010 and I'll have to say what a huge difference. Every time I could see an 18 wheeler approaching I would get ready for the back end to start to wag and it never did. It was a 4 hour trip with plenty of vehicles passing us and not once did I feel the usual wind effects of any type of vehicle. I also added the safe t plus to the steering, but didn't notice a big difference with that. When it wasn't windy conditions driving I thought the back and forth steering seemed less, but on the way back on our trip it was an extreme cross wind and I had counter steer a lot. I think they make an add on to center the steering from inside the cab in those conditions, but I didn't purchase that yet. But again, for what you're talking about the rear trac bar is exactly what will take care of the tail wag with vehicles going by.

Agreed. X2 on this. When you get it right the MH feels and handles like driving a big car.

I will have to say I agree with jrwalkerpa and atver that your motorhome should be set up correctly first. I'm very careful with checking air pressure in tires and air bags and had the alignment done to the specs on this forum. I was always happy with the ride under normal conditions, but was never satisfied with feeling I got when being passed by a vehicle, especially 18 wheelers. I figured for less than $1000 for the rear trac bar and safe t plus it would be a good investment for a better overall ride. The next thing I'm going to do is the Bilstein heavy duty shocks. Again, I'm happy with the overall ride, but under certain conditions some of these add ons make a difference.

Just drove over 1900 miles with 3050s the worst driving vehicle I have ever drove all over the road bags set at 70 psi let down to 45 psi drove better the last 400 guess I will have to carry pump find the best spot as far psi and add Rear Track Bar didn't drive this bad before the alignment tire pressure was perfect 75-80 psi 99% interstate driving open to suggestions

Did you align to the specs listed in this forum or just to Ford specs? You should have received post alignment (as left) data from the shop so you can post here or compare yourself to the specs recommended here. Changing air bag pressures can affect both caster and camber settings but only slightly just like loading of cargo and people in the coach. I measured my coach heights front and rear at the time of alignment and adjust bag pressures so that the coach's stance is the same when loaded at the beginning of each trip.

The alignment was done with about 2000 miles on unit to specs listed on forum fully loaded when aligned 70 psi in bags but so far my bags seem to leak down didn't have air chuck to fit them one at 65 psi one at 50 psi both at 80 psi when I left set at 45psi the last 400 miles seem to do better dealer said couldn't find leak before I left this was in a 15day period

Sounds like you did it right. If you verified the "as left settings" really meet the criteria on this site then other than something coming loose or the front stabilizer not aligned properly are all I can think of at this time. My shop had to align my stabilizer properly, the tech saying he sees them out of adjustment often. If the shop did not provide you with a printout of the "as left setting" then you really don't know where it is set. Modern equipment today generates the printouts so it's not something that can easily be fudged.
