Watch out for the 40 - 45' tour busses, they will want to pass you!
The road is pretty good, and my cousin had a difficult time keeping up with a 45' Prevost going up to one of the Lake Tahoe casino's. There is only one large public campground in South Lake Tahoe, I did not find any others. I stayed at my uncle's place down the street from the South Lake Tahoe campground. Across the street is Lupe's Burgers, they have great hambugers, the Lupe burger has a green chili on it (not to spicy).
Have fun!
There is a Costco with low cost gas as you leave lake Tahoe to Carson City. AS you go down that 4 lane grade, and get to the red light at the bottom, Costco is to your right, at the next signal. Several casino's offer great prices on dinners all over town.
Lake Tahoe is at aroun 6,500' elevation. As you aproach Lake Tahoe, make sure it is daytime. The views as you enter town are breathtaking, especially from the passenger seat of a class A, where you are well over the guardrail, and can see for a mile or so down into the valley below! My wife was driving, and we went back to take pictures in our car the next day!
