That's one thing I really like about it out here. You can pick and choose what you feel comfortable doing. Most of the places I take people to are 100% accessible by stock trucks (brought a bone stock Tacoma out there a few months ago) via maintained fire roads, but what obstacles you attempt at the fun spots are up to you.
And trust me, it is much better to be stock and go with at least one other vehicle than to do a bunch of modifications and go out solo. Plus, it can give you a good baseline on how much any mods you may want have improved your performance.
Thats great advice. I'm definitely looking forward to meeting up with a bunch of people.
