2022 190 how screwed am I? Rotting Wood

Noticed some ants In my camper as I was prepping it and making the bed. So I opened up the bed and removed the plywood to discover black ants in the front driver corner at the base of the wall. I sprayed some spray and tons came out… so that’s my first problem that I’m trying to figure out. Once I discovered that I noticed what looked like rust or dirt on top of one of the trim pieces that covers the wall panel seams and as I went to scrape at it with my nail the piece of trim easily popped lose. The whole piece peeled away from the rusted tack that held it in place. But now I can definitely see the trim is rotted and behind the wall appears to be rotting as well.

Not really sure what to do. Quite frustrated by this.

I do have the extended warranty but not sure if that’s gunna help me here.

Has anyone else experienced this?

Here’s a pic of the trim and wall

Okay good point. Looking at the back of the wood there definitely is some rot on it which would have to be from moisture. I noticed some bubbling on the opposite side of the window too after posting this so moisture is a r has been in the wall. Nothing appears wet at the moment and we’ve had two days straight of non stop rain so the fact that I didn’t see a big puddle under the bed would be a good sign too. But looking where the black ants were on the base of the floor and then the rotted piece of trim and then the bubbling it doesn’t seem good. I’m going to call the dealer tomorrow and schedule a service visit. I didn’t want to go ripping into that wall on my own if it’s potentially covered under warranty. Visual inspection of the seals up top seem good to my eye but I’m wondering if it’s from the widow window unit on the front.

Would the ants be after the rotten wood? There’s definitely no food. I’ve thoroughly cleaned this thing many times. There’s the hose used for winterizing that an under there as well but they don’t seem attracted to the dried up antifreeze on the end of that short line.

Thanks for replying and giving some slight hope.

So, I have an appointment scheduled for last month but the service didn't give me any confidence that this issue would likely be covered under the factory or extended warranty..
