I'm running an Optima Yellow Top with a 100w Renogy panel/air dam. I had a budget-brand fridge before, which was MUCH more power-hungry, so that led to my solar setup. It only survived 7 months, but left me with primo infrastructure to add a larger, more efficient refrigerator from Dometic. If I can park in the sun, I'm good indefinitely. Parked in the dark, I'm still good for 3 days or so without needing to start the vehicle. I have not yet had the opportunity to shake this fridge around on the trail, but in town it has been fantastic.
