Keep the potential for rolling the fuselage as long as possible.
Time to install a flap position indicator roll right 90 degrees and have at it. Wiring through the wing spar roll R or L and wire away. Parking brake, fuel lines, control linkage, panel installation.......... same story.
If planning your fuselage rotisserie, keep it low to the floor, (but the fuselage steps need to clear the floor).
