Hey there I have a 2018 amerilite mine does the same thing but I would pay attention to the drain
I would have water leaking all over the place and I couldn't figure out what it was
I even thought I was a pipe
Turns out the caulking around the drain and cracked because of the flex you are talking about and as ws approached the drain it would descend and water would gush out from around the caulking so I bought some silicone and now its.better than new
Hope this helps
