There are a few threads here about camping in the Model S but mostly about charging at camp grounds etc. Though a quick search also comes up with a few posts about needing an air mattress if you are actually going to sleep in the "trunk" I was hoping to get some personal experiences from those of you that have invested a little money into the "Camping Mode" option. What are the must have things to really pull it off with at least a little comfort (as opposed to sleeping on the ground outside the car)? Mattresses (What size)? Pillows? Blankets (or just use climate controls)? What is best for windows (blocking light as well as heat/cold if possible)? Tips and tricks? We did try it once at the Groveland CA supercharger a couple months ago, but we hadn't planned on it so we didn't have anythiing to help with the comfort level, particularly regarding the bump where the rear seats fold down.
