I was wondering about keeping some of my inventory in my van and at about what temperature should I bring the inventory in to avoid having it freeze.

Temps have been below freezing outside, but I don't think drinks would have frozen inside my company vehicle.

Is there a general rule I should follow?

anything diet will freeze faster than sugar. caffeine free diets will freeze the quickest.

17 degrees is what I am told sugar soda freezes at, 27 for diets. This is inside of a bay or semi delivery truck. I am sure the van would be similar as far as insulating factor. I wouldn't chance less than 30 if I were parking outdoors myself.

Thanks guys!! Those are exactly the answers I needed.

I made that mistake with some Sugar Free Red Bull, I forgot to take it out of the back of the van and discovered the next morning 5 cans did freeze and burst open.
