The van's round shape and random ridges/ cavities has made everything difficult, and trying to figure out how to build out the Kitchen Counter/ Cabinet area was a particular challenge. This past week I drafted up a plan for the frame in AutoCAD and stick built it to fit all the random changes in height and width. This required several adjustments to get it plum & true, but overall it turned out pretty good. I won't finish the siding or cabinets until I make decisions on the sink, cooking source, storage, etc. but having the frame in is going to allow me to work around it and finalize some other things.
