Do You Use a Cassette Toilet

No, the plan is permanent mount in a wet bath as found in the Northstar Campers. Some important advantages in a smaller truck camper (what I'm looking for) include addressing the TINY black tanks (8-9 gallons) in many campers requiring too frequent dump station finds. With a cassette you can remove tank and dump anywhere (outhouse, gas station toilet, etc.) without locating a dump station. You can also winterize your freshwater and grey tank system, but still use the toilet system with windshield washer (cheap) antifreeze. We did that in our porti-potti system on the Alaska Highway in winter. And we live in Wyoming and I hunt so there's that. Also, you can remove a frozen black water cassette tank and take it into a warmed area to thaw. Hard to do that with a black water permanent mount.

The experienced use answers I'm looking for are those of you who have used a permanent mount cassette (residential height) system in an RV.
