Hartland, Wisconsin....America's Home for Batteries
I'm at the same point you are...I'm planning out my rack so maybe we can bounce some ideas off each other. What material are you thinking of using? My roof is actually really strong. We have had 20 people up there before without an issue. This makes me think that I can use the wall studs as the supports, but also allow it to bow down in the middle a little to pass some force down to the roof ribs and panels (they are continuous from front to rear on a Wayne). My goals would be low profile, light-ish weight, and having fold up railings.
