The sites are wide and can fit at least 4 trucks on each site. There are a lot of trails to ride and no need for much 4x4 but it would be needed when snow comes down just in case. The trails to get to the sites are easy to drive and you are not hanging off an edge of a road like you would be going up a mountain. Just a heads up it's cold there during the summer around 65-70 degrees where it would be around 90-95 degrees in Fontana the nearest city or San Bernardino.
