We were "camping" at Seacliff State Beach CA last week and didn't have the sewer hose hooked up yet. The campground host walked by and was skeptical about our TM being self contained but we assured him that we'd stayed there many times before and that it was indeed self contained. They only allow self contained units there for some reason.
Got a lot of interest in the TrailManor this trip. One lady asked me if we were towing it with the Prius (we took the truck home and brought the Prius back so that we could buzz around in it).
I told her no, but that there was someone on our TrailManor owner's board who is towing with their Tesla.
