Let's see.

If you're using say 25 feet of 1" 80-20 for your frame, you'll save about .4 lbs over box.

40 1/4-20 bolts at 5/8" long, 8 of those corner fasteners (about .025 lbs each) and prolly about a foot and a half of 1" x .125" angle (at .2742 lbs / ft) gives you fasterner weight total of about .752 lbs...

<math skipped, have faith in my algebra>

So using 1" 80/20 for your frame is about 3.1% heavier than box aluminum, fasteners included. (13.17 lbs vs. 12.78 lbs)

Absolutely worth it IMHO.
