I'd bring the 80 and not the Scout! I get nervous just driving the Scout on a freeway let alone a trail.
The 80 has 35's, lockers, 3" lift. I'm not really worried about the ability of the 80, it's the driver that worries me!
You will be jsut fine. I have no problem calling for a strap when I think I need it even if others don't this will be a safe run and lots of fun.
