On our 3921 there are two hose connections down low in the convenience center. The left connection is the black tank flush for the front bath black tank. The connection on the right is the flush for the half bath black tank. No flush for the gray tanks.

Tank valve pulls for the front bath gray & black tank are in the convenience center. Tank valve pulls for the half bath/kitchen black and gray tanks have an access door about 6’ toward the rear from the convenience center.
