I am having a recurring problem on my 213. When filling the FW tank, by the time I know it's full, it's full, and then the fill and vent hoses weep at their fittings on the inside, under the front bench of the dinette. I have tried to cure it, But, at least for the fill hose, it never completely works. Those white and green fill hoses are hard to clamp tight enough to seal. I had the same issue with the same exact hose on a fifth wheel.
Now my carpet is wet under the plastic sheet that overlays the carpet, under the FW tank. When I get home I'll have to remove the tank and the plastic sheet, in order to dry things out. Jeesh. BTW the drips are just an inch or so from the simple 4x4 hardware store junction box for the genset wiring. The fill and vent hoses run right over the center of the j-box. This was poorly designed all the way around.
If I can't get it to seal, and I expect I won't since I've already tried everything I know, I'll start stuffing a towel in there, to be taken out at the end of each trip. I guess I'll line the whole area first with a garbage bag, under the towel.
Every trip involves quite a few little repairs. It's usually okay, but anything involving wet carpet and wood gets me agitated.
OK, venting over.
