Today I continued with the frame in the front left of the chassis. Takes a while, pretty fiddly to get this nice and straight.
I have checked some measurements from the plan and took some baggage doors to the chassis to double check positions. My wife and I and a bit of a discussion about pull out table in the front, table height, pass through shelf to the kitchen and door position and a couple of other things.
Looked a seating height with the pull out table outside, opening direction of the door and the placement of the door. I am getting closer now to the final check of door positions and openings.
