Attached is a description of, and dimensions and (minimal) materials required to build a level bed platform for Model S (2021 refresh) that folds and stows in the car, allowing back seats to be raised and access to the deep trunk compartment while taking up minimal extra space. Part of the platform detaches and folds to fit the slot for the cargo cover shelf.
I am 6'1" (185 cm) tall, and my wife and I have found it almost as comfortable as a tent. The low roof of the car is the primary drawback. It is more convenient than dealing with a wet tent because, even on a rainless night, condensation requires drying time. Most recently we used it on a road trip to the Arctic Ocean! Not the Ritz, but by all accounts better than the accommodations at Coldfoot Camp! Feel free to use and share widely without attribution. Let us know of your mods and experiences with it!
