I am a native San Diegan and this is what I can tell you - San Elijo is beautiful, but I have never RV'd there. I have heard that it is hard to get a spot there, but that is unconfirmed. As for the Julian area, I live in Ramona, 20 miles west of Julian. I have also never camped at Paso Picacho, but it is close. I would be happy to check it out for you. We just camped at Dos Picos here in Ramona this week-end and it was beautiful and very quiet.
