My parents’ RV, which they bought a couple months ago, apparently broke somehow today. The floor apparently started swelling up?? I don’t know how else to describe it, but it’s almost like it reverse-caved in. They closed the slide-out part and it seemed to get a little better, but when they look under it, there’s still something fishy so it’s probably gonna happen again if they re-open it.
Is anyone knowledgeable about RV’s enough to know if that’s a common thing, or something that has happened before? We have no clue what the cause could be, nor what the best course of actions is.
