I found this article tonight and thought it was very cool, wanted to share. I'm a little confused though, the past several years the mfrs have been selling us on frame stiffness and how it improves the ride and allows the suspension to work better, or at least thats what I believe they've been saying. But check out the frame flex in this article and how they describe their testing and how the flexible frame allows the wheels to maintain contact in extreme terrain. Seems like the frame is part of the suspension for these trucks. The pictures are amazing.
