Mine's a Starcraft 239TBS, so it's going to differ from the Roos. Jayco is probably closer. Under the side bunk there are 4 cabinet doors. Storage is about 6 ft wide, 18-24" high and a foot deep. Under the front bunk is single cabinet door for access to storage that's the full width of the camper. Above that, but still under the bunk, is a storage cubby with 2 oval openings for access. That's about 8" high and a bout 14-16" deep. I can fit an endless breeze fan laying flat in there with a little room to spare.
