5x5x3/16 is 185.4 lbs/20'. 6x3x1/8 is 143 lbs/20'. and 2x4x1/8 is 91.6 lbs/20'. If I build it from 3x6 instead of 2x4 it will be about #100 heavier. I'm wondering in the grand scheme of things that the extra ridgidity is worth the additional weight. Your frame is a basic ladder construction with additional tubular parallel members. With all that pipe doesn't the total weight almost add up to the same thing as I have? And there seems to be minimal cross bracing so how is torsional flex? Lots of research on chassis design and this type is on the bottom of the list. Just trying to make the best of it.
