Gerdo, which climbs are you referring to? Climbs such as Kenny's Climb on Fins and Things are scary the first time, then you realize that your 40 can do it and then they become fun! I have yet to do Launch Pad though, I know that's another puckery one...
To the OP, here is a link to the vehicle requirements for our Cruise Moab event, which is probably a good guideline for anybody - some of this information is a little dated though:
