Lake Tahoe was an interesting town. Because it is split between California and Neveda, it is two distinctive looks. RV parking is available at the casino's. It's done by first come first serve. Some casino's don't allow overnight parking, by sign, but don't really enforce it. We were there during 4th of July with no reservations. By luck we got into the campgound by the lake for 2 weeks.
Here's the campground. One of our favorite.
