Great pictures. Got a question about your rack system. What is it? How are those long rails attached to the roof and how do the racks attach to those rails? Are the rails thru bolted? When I had my Northstar TS 1000 roof apart for repairs I learned that the solid material stopped back from the edge and there was styrofoam to make the curved edge. I thru bolted Yakima gutter mounts on the sides of the roof and I've been relatively happy with it (4 cross bars) but I think the adjustability of your rails would be desireable. I typically carry canoes or kayaks up there. You may be able to see my system in this photo.
