Portable freezer

It seems like you're in the market for a solution to keep things frozen while you're on the move. There are compressor-based units available from various manufacturers that offer combo fridge/freezer or dedicated fridge/freezer options. Your choice will depend on factors like the amount of storage space you require and how much you're willing to spend. If you're looking for a budget option, there are electric coolers around $100-150 at truck stops that can help prevent food spoilage, although they might not be the most rugged. If you're open to spending $200 or more, a compressor-based electric fridge/freezer might be a more reliable choice, provided you have space in your truck. And if your truck already has a powerful inverter (at least 1200 watts), you could consider using a standard dorm fridge, even though it might take up more room.
