If you are talking about the mast, aluminum doesn’t work well, too bendy. If you want lower weight, use IMC conduit. The forming process work hardens the steel and it is actually stiffer than rigid pipe. It does have a welded seam which you might worry would rust, I haven’t experienced that though.

And doing the larger version of the M-TOW-P The question is, what size pipe? I had initially designed it with 3 inch pipe which is actually 3.5” OD. Looking at the pipe chart, 2.5” has an OD of 2.875”. The smaller pipe would be noticeably lighter to heft. Is that large enough to make SAF type mounts happy? Or would y’all rather have the larger pipe.
