We use L channel Aluminum makes for easy construction using our Hacksaw & Drill method, our entire frame was pop riveted together. We tried using box channel Aluminum in 2004 which we welded together (most of those welds broke and needed to be bolted back together) Also when we tightened stuff down the box channel tended to crush, we don't have that problem with the L channel. We built our main frame around the KOP drive train and just bolted it down. We did use wood as a base plate in the bottom of the frame because it lighter and easier to mount things to than metal (plus we have had base plates that were supposed to be Aluminum magically "transform" in to 1/8 inch thick steel plate)
