ours has the master bedroom in front and in the rear is a very large bathroom. the only other sleeping possibilities would be the sofa bed or converting the dinette to a bed. ours is a 2005
We had a Sunnybrook 3310 Double Bunkhouse for 10 years and are recently trading it in on the ST33BD. We always had a tent that we put our girls and their friends in weather permitting. They enjoyed it much more that being inside even though there were 4 bunks!!
