I used to have a 1972 Coachman camper. It had a forward wet bath. The front 3' of the camper was dedicated to the bathroom!
It had a drivers side closet, passenger side sink, with the toilet to the passenger side. open the closet door, and it closed off the hallway. The fresh water tank was just below that part of the hallway.
Behind the bath, the dinette was on the passenger side, raised about 6" to accommodate the black water tank. There was no grey tank in that model. Drivers side had the closet, then refrigerator, stove, sink, then a short counter before the door.
Sadly I have not seen any models like it. It was only about 9' long overall at the bed length, so it barely hung out past the fenders. It did have a cabover separated from the bath by 3 orange plexiglass sliding windows. (it was the 70's).
Good luck finding something!
Fred.
