I sleep in the back of my trucks. One has a platform for the mattress ( a fold up day bed style) that my gun case can slip under. I even built a small table to hold my clock and a coffee pot. Gotta have my coffee. Depending on where I am, either a 2200 watt genny to run an electric heater or a propane big buddy heater. Either way the genny goes along cause the coffee maker is electric. Food and a small jetboil stove is pretty much what I carry. And I do have a french press for those mornings I don't want to fire up the electricity.
