Just got off the phone with Fear...  To anyone that's doubting their rig, it's cool.  I'm open at both ends, and a friend who's done this has a bone stock '86 4Runner with 33's as his only mod, and he did fine.  95% of 5MP can be done with a bone stock rig; we even had a guy in a Discovery on bald ass passenger car tires keeping up with us on everything but the class 5 stuff.
