I have a 1993 Northern Lite
15' travel trailer (not made anymore). Bought last spring, camped in a few times over last season. We got rained on during a few nights, and ended up wet inside in various places. When I purchased the trailer I had noticed peeling paint
around the windows
, and the previous owner said it was from condensation. After a first few nights in the unit, it was pretty moist in there in the morning, so didn't think much of it. Then we were in a torrential downpour and water was puddling in the back window, flowing out of the driver side back window, etc. So, after the roof got a crack from snowload and leaked water all over the inside again, we decided this spring to fix the roof and in the process replace the wall panels that had the peeling paint
, and then reseal the windows
....this turned into ripping out everything. All the wall panel joints were hidden behind the furniture, so many many screws and pieces have been removed. This will be the first of probably many posts with questions as we fix and build this thing back up - so i'll get to the point.
Dealing with rotten wood:
The back driver side corner of the plywood 'subfloor', where the water flowed in from the crack, is still wet. Its still been freezing at night, so hasn't had much chance to dry out. The corner here is swollen, has ripples in the top layer of the plywood, etc. The front corner underneath where we had a bathroom vanity, the bolt that goes thru to the frame is buried in the plywood - like the wood is either swollen or bent.
Then there's the wood around the windows
. 2x2 - ish wood along top and bottom (doesn't seem related to the window at all, not actually sure what they are for - furniture/cabinets seemed to have been just drilled through the lauan and foam insulation and not the wood). The bottom pieces are in various states of mold/decay, from black speckles on fairly hard wood, to crumbling.
Do i replace the floor? It has 2 main parts, the raised bit under the dinette and the rest. Can i replace just pieces of concern? I would need to take the frame bolts out and this scares me.
Do I pull out and replace the wall pieces around the windows? Can the black speckle mold stuff be treated with a wood rot treatment? or better to remove? I want the foundation pieces of the trailer to be solid and never have to take it apart again. (its crazy how interconnected everything is!)
sorry for such a long post.
First 2 pics show the wood in the walls under the windows, from black speckly to crumbly. Final pic shows the floor where it is still wet from the recent roof crack.
