We have a Jayco 19RD (2015) and it has a similar floor plan. Most of the time there are two of us and our dog. Occasional there are 3 or 4 and it has worked out OK. Most of our time camping is spent outdoors anyway. Usually my husband is cooking meat over the campfire while I make the side dishes inside. One thing that is different from the one you are looking at is that when our couch flattens into a bed, the arms of the couch come off so the bed is bigger. I should mention that our kids are adults now and they were still comfortable with one on the couch bed and one on the dining bed. When there are just 3 of us the third person uses the couch bed. I LOVE the windows in mine -- one of the reasons we bought it!
