Nice game, fits the theme well and mechanics are implemented well.
It would've been nice for the camera to be free to rotate to survey the landscape instead of fixed to the facing of the truck, and maybe some survivor mechanics like morale, kind of like Frostpunk, where you have to balance people you save in the truck, VS supplies.
Hiding should also have some mechanics to do while waiting out the storm, so you aren't just staring at the screen doing nothing.
Maybe events like "found extra food" while doing inventory, or missing food and you have to find the culprit before the storm ends, or spending resources to fix a failing heater.
All in all a promising concept, would be really nice to see it expanded to a full game.
