Yup, and if I used rectangular tube and Carlos' cut-out method I bet I could bring the frame in at less than 1,222 lbs.
Let's say, using Carlos' method, I shaved 222 lbs off the total weight. I could easily be within 300 lbs of the original frame and that would be using 5x2 rectangular tubing in 3/16 gauge!
(My best guess is a factory frame is about 700 lbs. 60 feet of outrigger/cross-member material using 5" channel, .190" web thickness would weigh 603 lbs. I assume the factory material weighs at least half that or 300 lbs. 1000 lbs frame less 300 in outrigger/crossmember material. )
