Sway may mean different things to different people. If you have a lot of body roll (or sway) that can be corrected with a cheap handling fix if your F53 chassis has the front/rear stabilizer bars.
If you mean the coach wanders on the highway that is a different problem. I had my Precept 35S aligned before we picked it up at the dealer but it was aligned without cargo. Tires are at 95 psi. Installed a steering stabilizer and have completed the CHF.
Our Precept was all over the highway when empty, could not drive in a straight line. After the above modifications the "wandering" is not as severe and I can drive long stretches with one hand but it still requires my full attention when driving.
On our trip to TN last week my wife drove for an hour each way on I-75 and she still fights the steering wheel. I've learned to drive farther out in front of me and not to fight the steering but it still requires full focus.
On recent trips 8 hours of driving (with breaks) is pretty exhausting. I try to limit my driving days to 6 hours or less. Pot holes feel like the shocks are nothing more than iron rods, no shock absorption that I can tell. I think the F53 chassis is a poor choice for a motor home.
If we were full timers and traveled constantly I would either add ride enhancing modifications or trade it off for an air-ride commercial chassis motor home. As it is for a few months in FL and occasional trips in the Mid-west I can live with the ride.
