An hour or two of drilling? Maybe if I was trying to replicate the hole pattern, but I just don't see that much time used in putting a couple mount holes in tube. The time you lose cutting the tube so that multiple holes line up with multiple other holes would mitigate a lot time saved drilling in my opinion.

I could see the benefit of guaranteeing alignment with gussets, but again, only if you cut to the proper length. It is definitely a time saver to line up with gussets, no doubt, but you lose the ability to just get a length, clamp it to another piece, and drill right through.

My bad, replace the word "metal" with "mount hole". We tore the metal in a couple places our first year by having to drill multiple holes close to each other on some sheet metal. The metal itself held up, but the bolt in the correct hole tore its way over to a nearby hole and came out. That is what I was referring to.
