ARGH! Black tank odor inside camper but figured it out
Finally figured it out actually. Had checked the tank, then removed the toilet and checked the seal at the floor, THEN today removed the cap off of the plumbing vent with the intent of checking for blockages in the stack. And there it was ... ta da ...
The 1 1/2" black PVC extended all the way up to the bottom of the cap, effectively blocking the plumbing stack. No air could escape because the PVC was snug to the bottom of the cap.
So, I will trim the PVC to the top of the vent base piece, ensure it is a snug fit inside the fitting of the base (so odor can't go back down into the camper around the pipe) then replace the cap.
Wonder who installed that vent cap ... dumb-ta-da-dumb.
Looking forward to the camper not smelling when we stop.
