This is a great park, very quiet. Highway 94 is prett-8om Campo off I-8. Haven't tried the other way. There may even be a 40' restriction on 94 out there. Yikes.. it would make sense after that drive. Had FUH and was very reasonable, especially if you have one of the SD County senior cards. I did see one of the largest rattlers I have ever seen on a trail not far from the campground. JFYI. T-mobile and Sprint service was almost non existent, might work if you have a booster.
