Actually, I'd be fine camping a little bit inland away from the coast, on a few nights, so I wake up in sunshine instead of the fog. I live close enough to the beach here in So Cal that I have seen plenty of the Pacific Ocean in my lifetime, from San Diego to San Luis Obispo, I've fished quite a few harbors from tuna, to king salmon, to rockfish, ling cod, etc.
Don't per say need hook ups... take on 10 gallons on a 30 gallon tank at a time usually makes me good for 2 or 3 days, still not too heavy to trailer it. Usually after a week, it's time to use a dump station, and go to an RV park that has TV signal too.
