It's more typical to find 8, 10, or 12 gallon black tanks in Class B's so a
cassette type toilet or even a porta-potti might not be much of a compromise at all.
My van, with a cargo box on the hitch, is probably close to 22' feet now and I find that I overhang just about all parking lot spaces because of the cargo box. An extra 2 feet in addition to the 22' length (like when I add bikes in addition to the cargo box) really doesn't affect my choices of parking spaces much.
I'd prefer having the cargo space for gear and bikes inside the 24' length rather than hanging off the rear like I have to do now.
