I like Tahoe Valley(on the Calif side)...they have what you want and it's a pretty nice campground with plenty of sites that will allow your size rig. Not cheap but then again in Lake Tahoe, it's hard to find inexpensive! Within a couple of miles to the Lake(maybe less) and less than 4-5 miles to casino's.
