Pilgrim Lite Spongy Floor

Mine is soft over each of the holding tanks.

My 2014 Keystone Outback has a spongy floor in front of the regrigerator and stove. Believe it is also due to the foam and luan and how it is attached to the floor joists. This area is where my fridge and stove are in a slide so I can almost guarantee that that weight going in and out all the time broke the floor down. No signs of water leaks.

Seems to be a thing I guess. I have a '17 Laredo with the same spongy floor in front of the stove and refrigerators. They are in a slide also. No sign of leaks and I check it all the time.

My 2008 OFF-ROAD POPUP got spongy just inside the door and I'm sure that was due to water seeping in from under the door.

I adjusted the weather seal on my trailer door and added an angle metal strip under the floor to stop the spongy thing and see if it ever got worse. Still running with no change...

It's a common problem with foam and Luan sandwich floors. Had a Gulfstream Streamlite with the same issue.

Our 2007 RVision TrailCruiser hybrid had a foam filled floor but I don't recall it ever being "spongy".
