Hey Jack. Thanks for the message/compliment. We accomplished the 4th sleeper by connecting the single seat and the bench. So it forms an "L" in front of the wardrobe under the bed. Hense the shorter size. The 2023b lets call it, will have the 4th sleeper. B&B has 3 2023a's. We made the change in the next round of trailers. But yes, you could sit and sleep on the bench while the roof is down. Plenty of space......
