I recently camped in my new-to-me Model S using a setup that I originally used in my 1st gen Mazdaspeed3, and I found it to be pretty comfortable.
For the bed, I used this inflatable mattress and a portable 120V Coleman inflator and a Jackery power unit for the bed.
To fill the space at the rear lip I used two of these moving blankets as suggested in another thread (though I now see they are way cheaper at Harbor Freight).
For the head space, I created two platforms from PVC and placed them in the rear seat footwells. If you're interested in details on the platform, let me know. I have the front seats all the way forward, with a profile set for that position (be sure to deactivate key fob association with your normal profile!).
I covered the side windows with these screens and I use a normal windshield sunshade. Everything stores inside a 56 qt. Sterilite box. It does not fit in the subtrunk, nor the frunk, so I might try a different box.
I end up with access to the subtrunk, though somewhat impeded. The view from the inside looks like this:
It's very roomy. I slept comfortably in my MS3 with my wife and this has even more space. An advantage over the MS3 is that I can get in and out from the rear hatch, which I can open and close remotely, making things WAY easier.
