We have the Sunseeker 2300; you should look at one. It has a full size queen in the back corner. We ordered the optional mattress upgrade and it's great. The person sleeping on the exterior wall side has to clamber over the end of the bed to get out. Which is a bit easier than climbing over the partner.
You get the eating area, full bath, fully equipped kitchen. What you don't get is any other furniture. I would order the swiveling passenger seat.
Sunseeker Class C'sAnother suggestion would be the new Winnebago Travato 59K. It's a minimalist Class B with what looks to be good sleeping arrangements. I like it, but the price seems very high. Maybe there are good discounts negotiable.
