My Class C Majestic is loud and all over the road!

[Claybe]

We haven’t been on a long road trip in a while. I have done about 500 miles now on this trip and my daughters are complaining about how loud it is so I downloaded a decimal meter app and it measured 93 dB at one point! Anything I could do to quiet things down? Also, it is swaying all over the place. Should I install new sway bars? I have heard good things about the hellwigs. Thanks!

Sometimes the noise is associated with lousy roads - in my area the noise difference between newly paved road and old one is dramatic.

I am guessing you have a Ford chassis? First, check air pressure in your tires. Then take it to a real alignment shop and have it setup. Then look at shocks.
As for noise? Not much you can do. A full undercoat might help some. Most of the noise is stuff you cannot control Im guessing. Unless you start walking around while someone else is driving and start identifying squeeks, and rattles you are basicslly SOL.
