For your food, get yourself a cooler and cover it in blankets or something for extra insulation so your ice lasts longer.
What kind of vehicle are you in? The candle under a pot trick works somewhat, picture related, I've used it before. A doggo will also keep you warm if it doesn't get too cold but then it brings a new dynamic into your homeless life, and if you're sleeping in a sedan you can't exactly sleep with the puppers. Get yourself a good sleeping bag either way.
