OK now my head hurts, all those caps ;-)
I like the mid ship entrance into the galley, it just makes sense, considering most of the time you go in during the day will be for food or drink.
The head should also be located close to the entrance, another reason everyone goes in and out a lot.
I will be doing two slide outs at the front of the rig operated off a central mechanism that opens both using the truck air supply, at least that is the plan.
I will post more as my plans evolve.
