Lots of threads in the Class A Motohomes Forum. Some good reading.
You need to figure out exactly which issues you have. I find it hard to believe the suspension is bottoming out.
What chassis, MGWR do you have?
1. Weight of the loaded coach, front and rear; or better, each wheel.
2. Tire pressures adjusted for the tire manufacture's load and inflation tables.
3. Good frontend alignment, by a good truck shop.
After that you can look at suspension upgrade/add-ons. This should be done according to your specific issue(s)
It's a great time learning about all the systems in a class A MH. Good luck; try to take some comfort in knowing you are not alone in this "handling quest".
