In December 2017 we ordered a 2608SB which was the first model change from the previous 2608WS. The main difference is the door to the bedroom directly from the cabin instead of going through the bathroom. The bathroom in the SB therefore is smaller and lacks the additional cupboard behind the toilet. The door to bedroom in the SB (and the 2019BS) is a problem in that it overlaps the main slide and can get caught in the slide, if it comes open, when the slide is moved out. Don't ask me how I know that ... it was a very expensive fix!!!! The only other change was the location of the TV, which is slightly better in the SB.
We have no trouble accessing the wardrobe. It's a little tight, but I've never found myself needing to sit on the bed. I was impressed when I first saw the changes in the new model 2608BS. Certainly a lot more floor space in the bedroom, but, if I'm correct, this change eliminated the large pass-through storage in the rear of the trailer. This, to me, is a deal breaker. It also appears the bedroom window locations are less favorable.
If you've found a good deal on the 2608WS I think you would be very happy with it.
Just my 2 cents!
