Nice ride!
Free diamond plate is a good thing!!
BUT, I'm with 1bigtracker. You put that diamond plate on a big rock and you most likely won't slide over it. Even smooth alum. can be bad. It's soft and a good rock can goug it and hold you solid.
I've seen rigs where all it needed was the slighted push with one hand to help it along. Also watched a friend push a lock Sami on 33" back into a mud hole all by him self (with only his hands and feet).
So, some times it's the littlest stuff that makes the difference.
