Is that the one where they run a piece of PVC pipe from the black tank, through the bathroom wall into the space under the kitchen sink, and then run a length of dryer hose upward along the interior wall above the sink, to a vent fitting through the roof? I never liked the idea of running a bathroom vent hose above the food prep area or the clean dishes that I just washed. It was code-compliant, but as you say, not very attractive. On the other hand, I couldn't think of a better way.
