The triple deletes the rear window, and instead has a built-in hutch along the rear wall with a small opening for a drop table.
The DS has a much smaller TV cabinet where the fourth bunk used to be, and where the TS now has the fourth bunk. (Again.). The pre 2013 version of their big bunkhouse trailer had four racks in the bunkhouse. With the outside kitchen option, we lost the fourth bunk. That is, until they came out with the TS.
I'm guessing the DS tv cabinet will take much less tv than the TS back wall.
