I own a 2017 31FS. Jayco says it will sleep ten, which is only true considering the following. The couch that folds out can take two small children only. The overhead bunk could take 2 adults. The dinette can handle two people but not over 5'4 inch. Each bunk can take 6 foot. The queen bed which is a shorty queen, can take 2 adults, but any adult over 6 foot the feet hang off the bed. Transporting 10 people? Forget it. Enjoying 10 people in the rig? Forget it. How many it can sleep has no relation to how many it can walk. The people in the dinette can talk to the folks sitting on the couch, that's four people. Two other people can sit on the edge of the bottom bunk. Two can sit on the Queen bed in back. The only people really enjoying themselves will be the four at the Dinette/couch. Ten people cannot move around the rig comfortably. If you have that many people sleeping in the rig, you either must have the windows open, or run the air conditioners constantly. If you don't, the entire inside will be wet in the morning from exhaled humidity. I'm going to use a dehumidifier and there is only 3 of us. Good luck with how it works out.
