I believe in preparedness for disaster on long road trips especially in winter
I have a big rubbermaid box in the rear of the van in which I have a collapsible snow shovel, a new set of jumper cables, a blanket, a battery operated lantern, a gallon of -40 windshield deicer, 3 golf umbrellas, a first aid kit, a 6x6 ground sheet, several rain ponchos, a 40 gallon trash bag,a hagstrom map, a air compressor, a roll of paper towels, three bath towels, several bottles of water, 2 collapsible camp chairs and a frisbee.
