I had a tree branch come down penetrating my roof when I was a seasonal . The open hole allowed water to enter all week.
Just something to consider if your not there to see what is going on. Neighbors and CG owner were useless due to the blinders they all were wearing.
If you have the possibility of falling tree branches on windy days, it's possible for a branch to penetrate the thinner slide-out top or sides.
Maybe otherwise missing the TT entirely.
