I've had 2 RVs with 2 black tanks, both 5th wheels. An older bunkhouse with rear half bath, Prime Time Crusader, has no blank tank flush for the rear black. The regular black tank flush is in the wet bay. On a more recent toy hauler, Keystone Raptor, each black tank had a flush. The main black was in the wet bay. The rear half bath was on the right/curb side of the trailer towards the front. Quite a distance from the rear black tank but that's where they put it. Just a hose connection on the side of the trailer close to the fresh water tank vent. Point being it could be anywhere or not at all.
