Australians run 7-9 cu.ft 12V fridges in vans, using nothing but alternator and solar. No generator. Usually 180-240W solar - it's difficult to fit more wattage on the roof. Those are 12V fridges that need no inverter, they are expensive and a little more energy-efficient than fridge with inverter.
Your energy appetite is bigger because of electric kettle and grinder, both of them used frequently when in operation. Still, I would definitely add solar, in your location.

Will probably pay for itself in one year, considering saved fuel.
