Best floor plan for 6 sleepers

If you have young children, you could always get a toy hauler and convert the back space to a bunk room. My daughter's family have an older travel trailer (about 36') that has 2 bunks in the rear as well as a 2nd dinette booth that folds down into a bed. They keep that booth down so it's 3 beds back there and they have a front bedroom. The dinette in the kitchen area can be folded down if needed as well as a pull out sofa which is a double bed. These are used as beds for when their kids have friends going with them. Don't know if you could find that type of layout in newer trailers or not. They got rid of their 5th wheel to have more room for the kids.
