We were quite content spending winters in the 24VSD shown in our signature photo.
One nice thing was that it had the bathroom between the bedroom and kitchen/livingroom space. Good if someone visiting needed to use the "necessary room"... they didn't have to traipse through the bedroom to get there. Others have said that the "mid-bath" made them feel "trapped" in the bedroom, though.
If someone wanted to stay overnight, we could have (in theory) let them sleep on the fold-out sofa or made the dinette into a bed. We chose, however, to stick with the story that our ViewFinder slept only two people. :)
