Beyond the bath and a half, now most of the bunk models are two FULL baths.
Looked at the Dutchstar 4310 with two full baths then the 4326 with bath and half. I preferred the 1.5 bath, bunch of storage where the front shower is in the other and king bed instead queen. Even better though was the old 4313 with one giant bath and separate bunk room, basically the same as the Fleetwood Discovery 40G, but one bath is out of style now even in the gassers.
Really wouldn't like to have two separate dump systems like many of them do.
