Call the Forest Circus at South Lake Tahoe, talk with Suzanne. On the Eldorado, you should be able to camp, but not on the Tahoe. If you were more mobile that would help. Let me think about it as most of the area by Fallen Leaf is Desolation Wilderness, although you could go up to Floating Island, havn't been there in 30 years. They logged by Fallen Leaf, may have an option to just go in off the road there.
