We too have a ’17 NL, but Sportsman model; I think the plumbing would be the same. We have not had any problems with ours, but I find that the grey tank is shallow (to accommodate the shower drain) and the sensors don’t take much liquid to register partially full. Ours needs some slope to the rear to drain effectively. I would expect that even if your vents were plugged, unless your shower and sink drains were also plugged, the system would drain. Our grey tank is located in the basement, midship drivers side. If you remove the side cover just ahead of the drain compartment you should be able to see the end of the tank, and might be able to get a visual liquid level. If there’s liquid in the tank and it’s not draining downslope, I would try a snake from the drain valve.
