Van Items.... ?

Tent, tarp, sleeping bag, blankets, clothes, backpack, sterno cans for heat, electric heater?, canned food, cooler, water, gas can, flashlights, batteries, extra boots, small shovel, camping utensils, etc.

Sterno is alright, but I gotta say those little MSR stoves are pretty awesome. The knock offs from china are cheaper and work just as well.
 
I had a ton of shit in my van. All the normal "in case of" things. I had an air mattress which was awesome. I made a knight stick that I kept around. Binoculars, camera, maps, power inverter. Never underestimate the power of duct tape and crazy glue
