One or both in some cases are electric macerator Toilets ( think of a kitchen sink garbage disposal ) that grinds up waste and pumps it to the remote tank.
Our Winnebago Journey has the rear full bath with a macerator toilet. The half bath is directly over the black tank and has a conventional toilet.
If you do a lot of boondocking or stay in campgrounds without a sewer connection, the macerator is a bit problematic because it does use a lot more water. In our old Holiday Rambler, we could get around 10 day on our black tank. The new Winnebago only goes about four days using the macerator.
