The best part about RV living between San Diego and Los Angeles is that there are plenty of beaches to park. The only thing that’s a bit annoying (besides gas prices) is that there are virtually no truck stops on Interstate 5 or the Pacific Coast Highway in this area. That makes it difficult to empty black and grey water, along with refilling fresh water tanks. Truck stops are also great overnight parking spots that are easy to navigate in a large vehicle.
There are obvious conveniences that RVs offer that vans and Class B’s do not. But the one thing you have to get used to is not being able to just park where ever. A lot more planning and logistics are necessary with an RV, particularly those over 35 feet long. Many California cities have street signs everywhere saying its illegal to park vehicles 30+ feet long. Regardless, there are more than enough places to park for free. But even the paid beaches only cost between $15-$20 for 24 hours.
