Does anyone have any experience with a single grey/black tank. I see some of the newer units have only the one tank and would like feed back. I do not boondock so capacity is not an issue, I've never had anything but the twin tanks so need more information from those who have a single tank. Thanks

Owned a 1966 Avion with a single tank.

We camped in state parks without sewer, and used dump stations. It wasn't a problem.

Most trailers back then only had a single tank. As I recall, most of them had a black water tank, and the gray water bypassed the black water tank and just dumped on the ground. That became illegal around the mid 1970s.
I wouldn't want a combined tank because as you travel the sink and shower "P" traps will empty and the sewer gas from the black water tank will end up in your camper. The gray water is bad enough, but nothing like the black water.
