Bedding to 0° F is in the rooftop tent. In the back is soda, beer, snacks, a little tent to change clothes or poop in, a first aid kid with all toiletries, tools, a torch, a milk crate full of cured oak firewood, some flashlights, some battery banks, a jump box, some landscaping shears, paper towels, hand soap, dish soap, a single-burner stove, coffee, water... Pretty much, I'm ready to camp any time. If it's going to be for a long time, I bring a change of clothes, camp chairs, and a Zodi shower.
I just remembered there is also recovery gear and rain gear.
