I forgot to mention that we bought a Queen mattress and cut it into the two (narrow) twin mattresses for out Scamp
If I had to do it over I would make the beds 30" instead of 28" and think more on how to get storages boxes under the street side one.
The driver's side is given over to the utilities like battery
, Fresh water, Power, Hose reels etc.
The kitchen cabinets on the drivers side give a little longer bunk on this side.
The 24" refrigerator
cabinet takes up a little more space on the other side so that bunk is 2" shorter. (my side of course)
