Spongy floor

[Mikesr]

Noticed the floor is spongy on our 2009 Flafstaff TT
It's been setup for 2 years on a site in Delware.
At first I thought it was the stabilizer jacks being used this long but now I'am thinking it's the plywood separating due to moisture. The TT is in a semi wooded area and the humidity is high most times, the spongy is more noticeable in the front kitchen tile and the center bathroom floors. It may be under the care but can't tell.
I'am worried about the slides operating correctly since we leave them out.
Any thoughts? Thanks

This is what I found with my Streamlite and traded it after one trip.

What I did with mine was overlay the heavy traffic areas like the kitchen and bathroom areas with half inch particle board. I removed it when I traded it in. The lightweight materials that Flagstaff and their sister Rockwood used to lose weight was not always the sturdiest.

some of those floors were laminated foam so the bottom board retains moisture from the foam sweating and gets weak

More than likely leaks.
