Good lord but some of you pack a LOT! I'd never go anywhere if I had to take so much stuff but when I travel in my Cruiser, I'm alone and usually for no more than two nights. At 6', I just sleep on the floor with the middle seats tumbled forward which only gives me 5' of length but in decent weather I open the tailgate and use magnets to secure one of those Coughlan mosquito tents (it's a box shape and works pretty well). In inclement weather, I sleep curled up and turn diagonal if I need a little more length. I'm always packed for an overnighter. The photo actually shows more stuff than I normally take:
The green box is kitchen and dry food. The duffel is clothing, light down bag, bath, sharps, first aid, mosquito net, etc. The red day pack (paper plates, plastic cups, corkscrew, and, plastic bags), blanket, little green bags (Trekology chairs), and folded table underneath are picnic stuff for my wife and I. I usually pull it all out save for one chair when I'm camping. On the left, rolled up, is a comfy 25x60 sleeping pad. Misc. pillow, back cushion and two foam pads complete the load for inside seating at night. I also carry a little Anker BT speaker and LED lantern in the duffel. The Yeti is for when I take cold items but I don't always carry it.
I almost never make campfires and often toss a small telescope or spotting scope in the back. As I'm usually wearing boots when camping the shoes in the back are traded out for boat shoes (great moccasin for camp), there are a couple of trekking poles, and a lithium jump starter as well hidden in the pile on the right.
