Torque,
I know you asked for diamond plate input... ... but if you do decide to make the stainless steel Putco Master Boss boards an option, email me. Another TDR member (name on home computer) sent me several personal photos of these boards mounted on his truck. Very nice of him and very helpful to me. I will be ordering mine quite soon. BTW, the Putcos mount to the frame and body, just in case you're interested. I originally was looking at diamond plate as well, but, after messages about the quick weathering of the diamond plate sent me looking elsewhere. Good luck in your search!!
