Flooring/repair question

[Dave123]

I have a 2015 Lacrosse 318 that I bought new. It is at a fixed camp site. The floor next to the bed has started to get spongy in a 10”x10” area. This is the side of the trailer where the water connects. I see no water in the camper or dripping on the ground. I’ve pulled the underpinning and can’t find any issues. I can’t find a schematic of the trailer. Has anyone taken out the water supply box before? Are there a lot of gaskets there? Will I get a good view of the water supply line? I appreciate any help or suggestions.

Welcome to the forum its a great place to get your questions answered. As for a schematic of the plumbing or electrical those are nonexistent. It may not be a water problem and instead an area where there is a seam in the underlayment that needs to be shored up from underneath. let the forum know what you find.

Thanks for the reply. After several attempts at trying to find the issue without pulling the linoleum back, I pulled it back to find water damage. Not sure where it would be coming from . Could be the roof, could be the window directly above it. Leaks are too hard to track down on these things. Frustrating part is it’s four years old and pulled one time to my camping spot which was only 50 miles.

Have you ever done roof maintenance, like cleaning and recaulking the roof membrane edges? That's the most common source of water leaks.
