If no more rain is in the forecast, take the trailer out, open all the slides and let it air out. Ofcourse, you should call your dealer and make an appointment ASAP. I'm sure they'll take there time getting you in for an appointment.
We had a window gasket that leaked and did not find out until the wall was soft. We got it into our dealer found the window to be the issue replaced the insulation and the luan for $900. We were out of warranty. You should be taken care of.
Go enjoy your weekend, but I agree when you see that it is disheartning.
