Everything a first-timer needs: how Camp Mode works, what it does to your battery, what to pack beyond the mattress, and which mattress to start with for your model.
Every Tesla supports overnight sleeping via Camp Mode (climate + power stay on, ~8–12% battery per night). Fold the rear seats flat, add a mattress, and add window covers. Start with the Snuuzu Model Y or, on a budget, the Tesla OEM.
Easiest setup and pack-down, real-mattress comfort — the lowest-friction entry point.
Cheapest credible OEM-fit option for trying car camping before committing.
Comes as a kit — mattress, shades, sheet, bag — so you get the whole setup at once.
