Congrats on your RV. I know you will have a lot of fun with it. That being said, Two things you need to really look at to save future problems. First and most important, are the tires over 7 years old? If they are they must be replaced. A blow out can cause a lot of damage. The second thing is check the air bags in the front springs. If you find the front suspension bottoming out you could cause damage there. The p30 chassis does not have strong front springs and needs air bags to help the springs.
Do a Google on p30 front air bags and you will find a lot of threads on several forums about this. I put new air bags on the front of my 96 Aerbus and really improved it's handling.
Also on my couch I needed new main boards on my furnace and reefer to get them working. Not hard to fix but follow the diagnostics when trouble shooting as there could be other problems not the least could be mud dobber nests affecting the water heater and furnace.
Good Luck
