Then how are you to keep fridge cold while driving? If your refrigerator is a residential unit that requires 110-Volt 60-Hz AC power, then it needs to run off inverter. And an 1800-watt inverter should be plenty large enough provided you don't have other loads on it at same time. If someone here with more experience can't help you, I'd get a second/different opinion.
By the way, the fridge may run longer than a couple of hours on battery power if they are good. To know what to expect you'd have to look at refrigerator specs to see how much power it consumes. That and your batteries' capacity.
