When I car camp, planned for mid to late next month, I have a 10' x 15' cabin tent that sets up with tables, chairs, toilet, 3 beds with 4" foam pads, all the good stuff. Then we build a kitchen/eating area with a 12' x 30' tarp with sides. If we spend a week or so up there, we have quite the set up going on.
I would like to get a pop up tent or something (now I have the truck to pull it) but my money tree died.
Maybe some time.
