Best fix for common problem of water entry at bumper box

[Jeremy9107]

RFP. Consider us vintage (1970 Caravanner). Plenty of existing threads on rear floor rot and bumper box leak which is where we "borrowed" this fix, but ours was not an obvious leak issue. Just thought would address while was knee deep in renovation.

Believe problem to be water running off rear end cap and collecting on that flat surface that is the bumper box. It then travels under outer skin and first thing it encounters is a nice piece of water absorbent plywood. Do that over and over and you get rot. Our solution. Take out plywood and replace with rot proof Coosa. Now have installed this flashing so water will have to route differently.

Thanks for your reply, and accept my apology for my lame attempted hijack of this thread. My concern seems valid in what's-left-of-my-mind... reports of Airstream "fixing" the problem in, or around, 2012 is either true or it isn't, and, if it's true, it either works or it doesn't. I'm still confused (not exactly a news flash!).

I have a side question. After the job is complete what adhesive should be used to attach the vinyl/rubber strip back to the bumper guard rail.

The older trailers have a strip that goes in a slot and it does not require glue. I don't like the new trailer design with a glue in strip that is probably intended to be a one time use item and expensive I am sure. I don't know if weather strip adhesive would work well or not. Panel adhesive might be an option. Not sure how maintenance friendly either would be if you need to remove and replace. You could probably replace with the old channel if you wanted to be able to remove the trim periodically.
