A few notes on the Vehicle list:


- spare clothing pack
- food pack and biggish pot
- closed-cell foam sleeping pad (multiple uses, especially great for kneeling on when changing a tire)
- glad to see you're adding extra sandbags to give more weight in the back; a pickup with an empty box is scary on icy roads; depending on your load you may choose to carry even more
- don't forget extra sunglasses; the glare off snow can be intense
- water: I find the 2-litre soda bottles very tough and convenient; leave 20% volume for freezing; in a pinch you can cut the bottle off the ice block and melt it in the pot
- a couple of those flashing bicycle tail-lights; saves your main battery if you're stranded; important so you aren't clipped by another vehicle or snowplow
- windshield washer fluid (avail. everywhere); this contains alcohol to reduce freezing; also useful for washing parts in freezing conditions, but avoid skin contact
- methyl hydrate (called gas line antifreeze); you won't be using this with a diesel, but it's great for unthawing frozen locks and switches on equipment; avoid skin contact/vapour inhalation
- in remote areas, a good length of steel cable and a come-along can help you self-extract from the ditch (unless you have a winch on the truck); not fast but it works
- ? starting fluid: this is an ether/volatiles mix in a spray can, used to help start engines in extreme cold; I've used it for both diesel and gas engines in extreme cold, and it works, but spray in too much and you could blow the engine; not sure it's advisable for a modern pickup; but it's only a couple of bucks, and I wouldn't take a diesel off the beaten path in winter without it, if only for emergency use
