They did the same idiotic engineering on my 2015 8280WS. The black water vent pipe runs right through the AC ducting, and they didn't seal it, so AC was coming out from vent. I discovered it when I was replacing the vent cap and there was condensation all over it. I sealed around the pipe, installed the new vent cap, and dicor'ed all around that.
Hmmm, I suspect my 2015 8281WS is probably the same then, since so similar to your 8280WS.
I'm not clear exactly where you're talking about, but I guess this is where the vent pipe goes up through the roof, and you're referring to the in-roof ducting ?
Did either of you do sealing from inside the roof-space, using foam-filler etc ?
Any clarification would be greatly appreciated, since I'm wanting to improve the A/C effectiveness any way I can for our summer road-trip.
Thanks in advance
