I'm the new owner of a water damaged 2003 Kiwi M23B. I thought I looked it over really well and pushed all over it looking for soft spots and checked the roof for soft spots and bad caulk. The owner said it didn't have any water damage and never leaked.
After looking it over for the nth time I finally found a soft spot in the left rear on the outside (12" x 12"). Then looked in the cabinets at the same spot inside and found the floor and wall to be soft.
We called the previous owner and said it appears he didn't disclose everything to us and we suggested we bring the trailer back (<1 week). He didn't think that was a good idea and said his kids had spilled soda inside the cabinet and it is ridiculous to expect him to tell us "every little thing" that happened to the trailer in 9 years...then hung up on us.
The damage is localized to inside the cabinets and the square in the back rear on the outside and everything is dry now (even after weeks of rain in Houston). My plan is to:
1) fill the screw hole on the trim in the rear with Git Rot so the trim will hold again - just one screw. Is there solid wood to screw into at the bottom or am I just putting epoxy into styrofoam?
2) cut out the bad wood on the floor in the cabinet, soak the edges with Git Rot to try to save the wood that is under the walls and cabinet frame and reinstall new wood. Do I just glue down the new wood?
3) When time allows cut access panel under bunk on inside to drill into wall to inject Git Rot toward outside panel (fiber glass).
OR should I remove the trim outside and try to inject Git Rot up from the bottom through the soft wood? Is there a chance that I will open up a can of worms when I take the trim off?
Does this seem reasonable? Is there a better plan of attack? We bought an older trailer in fear that we wouldn't buy the right thing and figured it was better to spend $6k (I know we paid too much) than $15-20k and be disappointed. So if this old thing lasts 3 years I'll be very happy. Does this sound possible if I keep it sealed up (which I'm doing right now)?
Sorry for the long post, but I'm now asking all the questions I should have asked 2 weeks ago.
Thanks in advance for any advice or suggestions,
