Chuck: I've also considered options for using tubular sections that are collapsible or split along the axis of the tube to allow more room to carry other equipment in the car. Do you have the capability to form sheet metal? I've wondered about a large-diameter aluminum tube formed from two half-cylindrical pieces, joined with a simple flat joint at the seams. A couple of screws could hold the whole thing together. I've also considered beginning with cylindrical sections, then "carving" away as much as possible while keeping the strength of the cylindrical form intact. I've never seen such a tube, but I'd be surprised if it hasn't been done. Kim
