If you cross at the San Ysidro port of entry there is a place called La Pacifica RV Park 3 miles North on I-5 before the 905 , DO NOT stay there, a new corporation purchased the park and converted it into a trashy trailer park, really bad place, Police at least once a day, SWAT raids on drug dealers and narco transfer of products, gang members and graffiti, thefts of anything left out, they do not want caravans or overnighters only long term tenants.
Go further North to the Chula Vista J street RV place or the KOA on 2nd street or further North on I-8 in La Mesa or Santee Lakes.
