Van Roof Ladder Rack and Shelving? - van roof rack tent

Has anyone used heavy luggage aluminum roof. I live in Canada and asked www.bestnetoutlet.com Canadian manufacturer roof racks here, so if I also said that cargo rack, steel is not a problem, and it depends on the strength of the roof of the van was not himself.
I have also set aside my car, but there is nothing
Any idea which they set-aside made in Canada?
