"Also remember that California does not allow bringing fruits and they might check your coach for moths. The agriculture check station is East of Barstow, but they are building new one close to the state line. Don't get upset if they hold you there for some time. "

I run in and out of California all the time and yet to have seen a RV being held.

Yes, they ask about fruits, etc but it's fairly fast.

Could you explain "they hold you there for some time". Did it happen to you?
