The big feature of the 37KS3 is in the bathroom and bedroom. Rather then just having a small bedroom slide, Carriage lengthened the slide to include the bathroom sink. So now when the bedroom slide is out, the bathroom is by far the largest on the market. There are sliding doors on both sides to completely close it off for privacy. The bathroom counter top is enormous, there is plenty of space toiletries. This new layout is sure to be a great success, you will not be disappointed with the amount of space available.
