First thing to consider is the tire pressures. Get your coach weighed and set the pressures according to the tire manufacturer's pressure chart.
My coach did the same thing when I got it. After considering and checking everything, I found that my sway bar bushings were mostly gone. Replaced them and the sway issue was gone. My suggestion would be to replace your sway bar bushings...even though they "look" new, they could be hard or deteriorated under the strap. Go with these:
Poly Sway Bar BushingsBe sure to clean the sway bar really good of any of the old bushing material that may be melted onto it and use the included lube packets inside the new ones before closing everything up.
Next thing to check are shocks. Unless they are leaking, you can't tell by looking at them if they are bad. Bad shocks usually cause a really bouncy ride overall. Their sole purpose is to dampen the bouncing that occurs when you run over uneven surfaces and bumps. Shocks could well be the problem, but if sway is your only complaint, then start with the sway bar bushings and tire pressures.
