We have a typical 27 footer that has a rear bed with access on the right side and at the foot. Bed is crosswise in the rear bedroom. There are a few rigs in this range that have beds mounted with head at back wall and a slide to give access on both sides. It's a PITA to make our bed and to get into and out of without disturbing person on the right. We use a dual Trav-Sac instead of making the bed which helps a little. You can dispense with most RV inconveniences if you buy a behemoth Class A as shown on "Go RV" TV show.
