haha I've slept in mine plenty of times.
I like to keep it discrete. My back seat splits so there is one wider side. I use that as the sleeping side. I keep everything else stored to the smaller side and make sure to always keep the roll cover closed when the seat is up so that people can't see my stuff. Then I keep the areas behind the driver and passenger seats full of stuff I commonly use. I throw a pillow over both sections or a blanket during the day. If I have skis in my car while this is happening. I put them behind the passenger seat angled in so that they don't go in the trunk at all and fit nicely behind the seat.
2 sealed plastic containers. One for trash, one for dirty clothing. I also recommend a third plastic lid for a plastic tub. Not a tub, just the lid. reason for this is that you can set wet boots on it and what not and the water just runs into the grove of the lid so you can take care of that later. also, if you hook a hanger in the back, you can put the lid under anything that is wet like swim shorts or whatever and it will dry quick and your car will stay dry.
