I'll assume you might not want to do city traffic all the way through San Diego and up into Orange County to the Los Angeles area. These are some very broad strokes without much detail since I don't know what route might interest you.
Right after you cross at Tecate there is a county park just to the east on route 94 at Potrero. That might be too soon for you to stop for the day though. You have a lot of time to kill between Tecate and Los Angeles. You might want to head on east on route 94 to Interstate 8 down into the Anza Borrego Desert State Park. Some nice camping there and also lots of boondocking opportunities. From there you could work your way up past Palm Springs to Interstate 10 and go west a bit and then head up into the Big Bear Lake area in mountains on route 38.
Or from Tecate you could work your way up to Pine Valley on Interstate 8 and take Sunrise Highway (S1) up to the little mountain town of Julian on route 79. From there you could also drop down into Anza Borrego Park. Or you could continue working on north up past Warner Springs on route 79 all the way up to Temecula on I-15. Or cut off to the east at Aguanga (route 371) over through Anza and head on up to Idyllwild on 74 north -- another mountain town but without much RV parking at all. From there you can drop down to Interstate 10 (on a really long steep grade) or you can back track a bit and drop down out of the mountains into the Hemet area which puts you over near I-15.
If the ocean interest you then it's city driving and some somewhat expensive places to stay all the way up to LA.
Just north and east of the border, in Campo, there is a train museum, don't know if you are into trains or not, but worth a look if you like them.
You should be able to find several boondocking areas in that location. There are even a couple of off road recreation areas, you can dry camp there free.
Along he coast, there are a few state beaches, several are dry camping, near Oceanside is a nice one, it is on a cliff that overlooks the beach about 100' below. It is close to San Onofre nuclear plant (that is closed this month).
Dana Point is another State Beach, so is Huntington Beach.
We would stay inland and go thu the Salton Sea area. Lots of places to see & boondock, Slab City for a night just so you can say you have been there, boondocking at nearly all the Casinos,several State & National Parks and make your way into LA via the 210. Much easier drive and more places to boondock. Traffic is nuts up the Coast, have done it toooooo many times.
Good luck and don't forget us on the Traveling in Mexico forum.
