I think we should be pretty good. The floor crossmembers are made from 3/16″ c-Channels, and the external frame is made from 3/8″ wall 2″x3″ Tubes. Of course the entire structure will act as a truss as well, reinforcing the overall strength, but all you can see is the floor so far.
btw, We’re planning on doing the mount stress tests in the next couple of days…
