Is this what to expect from Firest River?

[Hollywood16]

Bought a new Salem LE 22FB Northern Edition back in 2007. My family goes camping 3-4 times a year. Always winterized and well taken care of.

Last year, I couldn't figure out why the Lino was discoloring and thought it was wear. Last week during a camping trip I noticed the floor by the door to be soft. Now i know some people would say,"What the hell did you do to your trailer?" or "maybe you should have taken better care." Well i challenge anyone to come and have a look at how well this trailer was maintained . So tonight I decided to tear up the Lino to replace and found nothing but mould and rot. Apparently it was completely past the engineers at Forest River to consider some sort of venting on the fully plastic sealed subframe. So somehow over the years moisture (I counted two pints of moisture) has now drained from the soaked insulation. Now to figure out how to rip up the floor in a five year old trailer. I am hoping for some suggestions.

I'm guessing it either came from a plumbing leak or came in from rain above.
I know that doesn't help you but that's my guess.

My trailer has had various plumbing leaks over the years.
Started with a loose fitting on the back side of my water heater our 1st trip out.
Found wet carpet around the bed day 1.
I've been able to locate and tighten all of them with no real damage but a tiny
drip under a sink or shower can do a lot of damage in 5 years.

Good luck with your repair of the floor but you also need to figure out how
all that water got in there. I don't believe it's just condensation due to the
enclosed underbelly.

Feel for ya. I rebuilt the bottom of 2 slideouts on our Breckenridge. Moisture was accumulated condensation collecting on top of the waterproof plastic bottom. Rotted out badly with a lot of water trapped upon discovery. Moisture, regardless of the source, could not escape once it got to the underbelly. I also had to rebuild the entire bathroom floor. Water had run down an awning arm, through the lag bolt holes, and into the wall at the baseboard trim level. Hindsight 20/20, I should have tried to claim it on my insurance. One question I have is what are your walls made of, fiberglass or tin sided, block foam or fiberglass insulation. Condensation seems unlikely on yours with the doorway there. It took me a day and a garden hose to find our water source at the bathroom door area. I see now on our new sandpiper fifth wheel the say to check all caulking and gaskets on the entire trailer every 6 months. Good luck to ya.

This is not an exclusive problem to Forest River, I can guarantee you that. About any camper will leak, even with the best of maint. it does happen. I am in the process of rebuilding my bathroom in mine right now and it is not a forest river. Some advice, if you have some know how in working with wood, it isnt that bad to fix. It takes a ton of labor but it is self explanatory once you get it open.
