is this my rear leak source?

[calgary68]

I have a '68 safari twin and after a few days of rain, I found the interior below the sink to be fairly wet.

The seam above the area seemed damp and it looks like water could be running down the side of the window and in through the corner, just outside of the curved edge of the window seal... make sense?

I have another challenge in that corner as well, the bumper took some kind of impact and is detached. I don't think water is being pulled up in this area, but it's likely not helping the situation...

Thoughts?

Very probably. That seam where your rear wall meets the bumper is also notorious for drawing water right into the endgrain of the subfloor. Maybe not so much in the 60's era trailers as in the 70's but that weakness is still there.

Unless you know for a fact that the bumper was hit, I would be more suspicious that you have an advanced case of rear-end separation and that the floor under the rear wall has rotted away, any bolts connecting your shell to your frame have disintegrated, and you now have a frame that is no longer supported by the shell, at least on the one side.

good luck!

I had started another thread on the bumper, while I am convinced it was hit as there is a frame repair weld just behind the tire, I am reluctantly coming to the conclusion that I have rear end separation. I did the bounce test on the other side and the frame does move a bit independently of the shell... argh.

I did plug up the corners of the window though and will test this weekend for the seal. thx
