Went last year...was an awesome experience...its pretty much pay as you go so you can come for part or all of the event, its up to you...and as far as your truck being near stock thats fine too...there are too many trucks there to run in all one group so they are divided up by types of trails you want to run...It all depends on what you and your truck feel comfortable with...everything from muddy fire roads up to trails where you can be pretty sure someone in your group will do some sort of major damage...By all means come on down!! You're guaranteed to learn something and have a great time!!
