Rev,
You must have missed my post about the same thing a few months ago. I thought that was the magic answer but since the wallpaper problems were happening on both sides I didn't get too excited other than to fix the problem as you did. Just plain dumb what they did when they put these together with no thought whatsoever. I noticed a brand new one at the Pomona RV show and they put the hole for the awing electric at the top instead. No sealant whatsoever this time.... just an open hole.
