Ive got access to a cabin down the road from Buck, but we decided to go back to our camping roots..
Not saying it is the end all, be all, but there is a good campground on Lower Buckatabon. Buckatabon Lodge. If you go there, you will have great bass fishing, great panfishing and trophy musky water. With a lot of weeds to fish as well as drop offs and water that isn't as clear as some that you mentioned above.
Never been there, but I hear that the Turtle Flambeau Flowage is gorgeous and has a ton of great camping sites on it. That would probably be as close to a true wilderness camp as you can get.
Lastly, I think that there are some nice, remote campgrounds in the Sylvania Wilderness tract up near Land-O-Lakes. Lots of lakes around there (for canoes/kayaks) that are full of smallies. Again, that would be a very remote experience.
Good luck to you!
