Kitchen hangs on the outside. That's the shower cutain on the left
bunk folds up against the wall, for now guests use a cot.
It'll hold 3 bikes easy, (shower test in progress)
Shower in use
It's a 6x12 vee nose, you can haul larger ones with a half ton truck but I don't want to and this one is adequate for my needs. Water for shower is heated by a propane camp heater, gravity fed from a container on the roof, through the heater and into a container on the ground. Then the container on the ground is placed on the roof and rub-a-dub-dub.
Surprisingly, the 7gal container spewed water uninterrupted for a full 20 minutes.
