My wife made the mistake of peeking in here. I am redoing the center section from the bath to the drivers seat. Next year the bath and bedroom and probably the cab over.
Using the old insulation to lay out the new roof ribs.It was molded to the old ribs and I managed to get one nice tapered piece out intact.
six new ribs in all with new insulation.
Doug fir 2" x 1 1/4" screwed to the top frame rails for the new ribs to set on.
Each rib sets on the new side rail, and then is anchored in with angle iron. All this will be hidden behind the upper cabinets.
