Road trip tip for when you guys start travel prepping again: frozen bottles of water are often more useful and cheaper than ice packs. I save a few old bottles, fill them up from the tap, and freeze them to use in cold bags to keep foods and drinks chilled. I can still use the bottles as ice packs for injuries too but I can also drink the water (on its own or with electrolyte or other mixes), use it for brushing teeth and washing off, or have it on hand for emergencies. Obviously, you can filter your water or use whatever water you'd like, but having water on hand in general is always a good idea - perhaps an obvious statement but also easy to forget and important to remember.
