After it cured I trimmed away the excess, added Dicor and installed the vent covers.
I hope this clarifies the work I did?
Sort of ... I'm not exactly sure where the vent pipe runs. I'm guessing it's in the corner cabinet in the bathroom ? I'll take a look next time I'm at the storage lot.
If so then I guess to seal the bottom you do it from inside the camper ?
Also sounds like there's an outer sheath around the pipe ? (is this what the vent cover you refer to is ? or do you just mean the cap ?)
I'll take a look maybe this weekend, if I get time to head over there.
Thanks for trying to clarify
