We just purchased our first class a, it has a automatic leveling system that when down "creaks" all the time. service said it was probably from the wind...any advice?? is this normal or a concern??

In my owners manual they recommend blocks so jacks don't over extend. I've found that using blocks stops some of that creaking noise. Seems like the more the jacks are extended the more creaking I was getting.
