My 1st night, I used the stabilizer jacks to level the trailer and then couldnt figure out why all the doors and cabinets wouldn't open/close properly when they were all fine at the dealer less than an hour before.
I thought for sure that just the 20 mile drive from the dealer to campground screwed everything all up.
Fortunately I figured it out after a little while and releveled using a board on one side. No permanent damage that I can tell. I just use the stabilizer to stabilize now.
