Our lower frame is made out of the KitBot material with most of the frame above made out of 8020. One of the benefits (and drawbacks) with 8020 is that you can fairly easily slide pieces around for adjustability. To deal with the twisting issue not only do we have cross braces in the front but at critical points we had to drill through and bolt components together. This is something we learned about 8020 many moons ago so we know how to deal with this now. Here
is a link to some pictures of them.
