I thought it had to be 10L to be a big boy? Nah just kidding. Gulches is a very well designed park. Your SUV will have no problem getting around to the big stuff like 3d and testosteroid. There are some good trails to test your SUV too even though its on 31s.
ok cool. I know my place i am no longer in the big boy class. Got my little rango with some little mud tires to watch the big boys do what they do best. LOL
