Wet subfloor and floor insulation

We are fairly new to this, we bought a used camper trailer (it's a 2005), and after 2 seasons, we found a "soft spot" in the floor. Handy Hubby pulled up the linoleum and found soggy, wet, rotten wood under the linoleum - he started the demo, and we can't seem to find the end of it. We have pulled up the front half of the floor - back to the kitchen cabinets and refrigerator and the insulation is still soaked on the bottom. Is this normal because the insulation is between the linoleum and the waterproof bottom belly fabric so condensation caused by a warmer living area can't escape?? We live in AK, so we do use our heater. How far should we go with this?????

Not sure what kind of trailer you have. Is there a slide out involved? Sounds like there is lots of damage and depending on the amount you may be better off scrapping it. The walls could be damaged and that would be even worse. Go as far as you have to to determine the extent and then figure out how much the repair would be. Since you are going to do it yourself your costs won't be as high. Good luck.

You will probably chase the rot all the way back to it's source leak, usually the roof. It then will travel down a fafter to the wall and eventually end up in the floor. You just noticed the floor but will most likely need to replace far more wood and insulation.

Check the roof for cracked caulking around vents, AC, skylights and seams twice a year to prevent further leaks. Use eternabond or Dicor self leveling caulk to seal it up.

First find the source of the moisture. Then do a cost estimate of the repairs. Several people have done a Total Rebuild. Only you can determine how much you want to invest in having a 'new' camper including labor.

Having some experience doing this type of repair, like others have said, only you can decide how much to spend. My rule is.... does the repair cost more than 40% of the purchase price, and if so, will the repair add value to the rig at all?. If these questions end in negative values, then I would dump it. This is not condensation. You have a roof, water pipe, vent or window leak somewhere, and it's been that way for awhile to do that much damage.
Best of luck as you move on to your decision.

Live in Alaska as well and condensation is an issue in cold weather but not enough to cause the kind of damage you are describing. Find the source of the water. It could be something simple and easy to fix. Roof leaks are another issue. They can be hard to pin point just where it is leaking and will likely have cause additional damage. Hope things get better for you and not worse.

Check out the thread "Total Rebuild". Terry totally rebuilt a 5er into a toy hauler. Will give you an idea about the scope of work.
