I mulled it over for years, how to camp in my Insight. Finally one day I saw a big sheet of plywood that had been between a mattress and box spring, but had somehow made it into my garage. I push the passenger seat forward as far as it will go and put the plywood over the lip of hatchback bed behind the seats, therefore extending the hatchback. I tried Thermarest type camping mattresses, and was more comfy with a firm 3-fold foam mattress. And sleep diagonally. I had had previous attempts without the plywood in which I was forced to curl up in more of a fetal position than I prefer. I went to a retreat that was so full I would have had to share a room with a nice mom and her great but way too exuberant 7-year-old, so the car won out. Other times I have felt too lazy to put up a tent and used the car. I have also slept across the 2 seats, with a flexible camping mattress, thin foam over the parking brake, not as good as the plywood solution. It helps that I am small, about 5'3". I saw a video a while ago of a very big guy who made a platform that reached to the dashboard of a first generation Insight. The best part was his partner's giggling. I will add a photo.
