Do the work to the box first. Vents in the roof, passage cab to the box and any changes to the walls, floors and ceiling like adding any insulation and /or paneling. Windows if you still want them. I like the idea of the bathroom in the rear on a raised platform. Roof of the box should be high enough to allow that. Tanks can be under that platform with access to them via the rear door.
One big issue is power. You are going to need some kind of power generation. Generator? Solar? Running the truck to take a shower would be a little expensive.
