After you adjust the air pressure and get the alignment (every new car I ever bought was out of alignment when i bought it), get a SteerSafe and see where that leaves you. Next steps would be the largest sway bars you can get and a trac bar. I don't know if a shock upgrade would be necessary on a new coach.
When I got my 02 Winnebago Sightseer, I couldn't hardly keep it on the road. Alignment and tire pressure helped a lot. Higher tire pressures do not help handling. SteerSafe took it to another level. Mine did require 1 adjustment. I installed every handling add on I could find on the internet. After all that it handles very well. Henderson Bell cranks, Henderson front springs (no airbags), SteerSafe, polyurethane sway bar bushings front and rear, Bilstein shocks, rear trac bar, and timbren type helper springs front and rear (because I couldn't get bigger sway bars) and a few other things that I can't remember. I kept telling myself that even owners of new units have to go through this. Looks like I was right.
