Thought about that also. For 2 adults, a queen sized bed ("80x60") is needed as a double (75"x54") is just too small for more then 1 or 2 nights of crowded sleep.

With the queen mattress being that size, there is not a lot of maneuver room to be winching a mattress up/down from the ceiling etc. The original plan with the 7x14 trailer was to have the mattress across the back and 2' off the floor with the space underneath used as storage.

Anyone have any other ideas?
