RE: I need an airplane rack system for my van
AEAJR I would make totes out of 1/2 or 3/4" pVC piping. Just use "T'S" and elbows for the body. Cover the frame where the plane parts touch with pipe insulation. I would make carriers to fit the planes as necessary. If your seats fold down you are in business. Just make up your carriers and put them on the folded down seats. friction from the pipe insulation and the fabric of the seats should keep them in place.
