I suffed some more areas of the interior which will be getting primed, then painted. Since I would have a heck of a time painting between these brackets, I just drilled them off so I can paint them independently. I'll reinstall them once the interior painting is done.

Scuffed the side rail all the way up to the sub panel.

Fitted the baggage bulkhead to figure out where to cut a notch for the dog platform center support.
