My Shasta came with a walk around queen or with the bed across the front (head on the drivers side under the emergency window and one person sleeping next to the front wall) which enabled bunk beds. I went with the bunk bed version.
I am so glad that I did that. My husband has so much more room to enter/exit the bed. Once he swings his legs off the bed he has a straight shot to the bathroom, too. He was actually worried about getting in and out of bed of a walk around with his limited mobility since there is not as much room between bed and wall as there is in the bedroom in our sticks and bricks.
As for me who sleeps against the wall - our TT sits on top of the "basement" and there is a little space at the foot of the bed that indents sllghtly. This lets me access the bed by standing at the foot of the bed. I put a two step stepstool there and I have no problem getting in the bed, or changing the sheets.
The floorplan link shows this better than I can explain it.
