That looks to be a nice setup, their box might be a bit larger than ours as they are sleeping fore/aft which takes more length (for us it is 80" x 60"). We can not afford to lose 20" (our interior is 16.5'). The other problem I would run into is I am placing our washer on the wall under the bed, so no room for inset steps. I guess all these designs are a trade off and I am by no means an interior designer (and I am sure I will miss things). Really love the overhead skylight though, if I could have afforded it I would have had one made and shipped to us.
