Ugh - Water damage!

So it is rainy season here in Florida, the coach has been sitting at home for all of 2-3 days and I see this -

The counter is cupped. The edge of the sink is not touching the counter anymore. Great. Also parts of the dinette chair is wet/stained. Hint to future buyers, look at all stains carefully! Apparently there were/are multiple leaks. I start peeling off the green carpet to find water destroyed wood panels.

Wood has delaminated
