Yup! Tire pressure and alignment first. When properly set they make all the difference in the world.
But, you will still get buffeted by the wind wall of passing big rigs and other RVs. If you are a weekend warrior, it's probably not an issue, (most likely the thinking of every motorhome manufacturer). However, if you are a fulltimer, or just picky, then you will want to modify things a bit.
Here is the list of suspension modifications that you might start investigating:
1. CHF - The "Cheap Handling Fix".
2. Steering Stabilizer, (Safe-T-Plus, TruCenter).
3. Rear Axle Stabilizer Bar.
4. Shock Absorbers, (you likely don't need this one on a new coach).
Some people perform them in different order, or skip some.
