OP, install larger Roadmaster swaybars to decrease sway and you can go to Koni FSD shocks for a smother ride.
We have a 2018 Alante 31V and it DOES have the 2-hole sway bars.
We also experienced a fair bit of swaying when windy and being passed as well as road wandering, requiring constant steering corrections.
We did all of the following:
- Added steering stabilizer. This improved the steering feeling subjectively and is supposedly safer in case of a tire blowout but I believe it did not make a difference in terms of swaying and wandering.
- Added rear axle trac bar (panhard rod). This did improve the movement of the coach in terms of swaying.
- Did the CHF . I believe it improved the swaying somewhat but made also the bumpiness of the ride on bad roads a little worse.
- Wheel alignment by a professional truck tire shop. They found the factory alignment was quite a bit off and corrected the toe-in. That made a major difference in terms of wandering.
In summary, I am o.k. with how the MH drives now. That said, it is still a big box on an ancient chassis design and that shows.
- If driving on a flat and smooth road on balmy day, I can let the steering wheel go and the coach will track nicely down the road.
- If the road is crowned or there is cross-wind, it will definitely track to one side.
- If the road is rutted there is significant tramlining, i.e. wandering and required steering corrections
- Passing trucks can still push the vehicle noticably to the side, requiring a steering input. But the latter seems to depend on cross-wind as well because sometimes that happens and sometimes not much, independent of the size of the passing truck.
I kind of got used to it and after a while the steering correction becomes part of the routine.
Edited to say: While the whole vehicle is 2018, I don't know how old the Ford chassis is. It may well be from 2017 or even older.
