There are some things to check and some to improve. Make sure your tire pressure is as suggested. Your wheel alignment may be off. You can improve the front end sway by making the sway bar tighter (as described by Rmexline). Part of the sway you are experiencing could be related to the rear end. Our coaches have a LOT of rear end. You can install sway control such as TigerTrak by Blue Ox or similar to reduce or eliminate the sway.
We've done everything but the wheel alignment. I'm going to contact FR this coming up spring to get ours aligned. It rides pretty good, but due to what others have been experiencing, I don't have a warm fuzzy that it is within specs. Tires are expensive and we don't want premature wear due to a bad alignment.
Drive safe and log some miles in it. The more you drive it the better you get at predicting corrections for wind, passing trucks, etc.
