Does the south camping ares (south of 36) fill up simultaneously with the north 40?.
They are distinct entities.
There are essentially FOUR parking areas at Oshkosh:
1. Homebuilt (also called custom) which is along the 18-36 starting from the comm center north until it hits the warbirds, then it turns left and runs west. Camping is on the part that is west of warbirds.
2. Warbirds, no camping, tucked into the corner of 9-27 and 18-36
3. Vintage, which runs south from the comm center along 18-36 to the south airport boundary including a patch east of Wittman road (and south of the Theatre in the Woods). Various areas are carved out within Vintage for pre-WWII stuff, special displays (like the Valdez STOL ships and the Post War Boon display), parking and camping.
4. The North 40 starting from warbirds and wrapping around 9-27 until you hit the terminal building. Camping starts from the warbird end and parking starts from the terminal and the boundary is somewhat fluid.
Obviously you need to be a Homebuilt to park in #1, a warbird to park in #2, a 1970 or earlier to park in #3 (though we will take some homebuilt campers), and anybody who wants (or can't qualify elsewhere) to #4.
(of course there are a few more: the west ramp and display area, Basler and Weeks if you have prior permission, and the Ultralights)
