Floor 1 - I would take out one of the bathrooms between the bedrooms and the wall for a Jack and Jill bathroom. Also needs a big shower in master bath, and not crazy about the master suite sharing a wall with the living room.
If you have the wall space in your RV gain two extra sleeping spots, with this space saving Bunk Bed Gadget. I'm thinking wall in garage of toy hauler RV separating living area. Or a great opion for a small bedroom for brothers or sisters!
