Looks like a great fridge. I have a FSR EVO2 hardshell RTT like yours. I mounted 2- 200 watt CIGS solar panels to the top of my roof. They are very flexible and durable and can be glued right on top of the shell leaving the crossbars available for other stuff. These panels are not as affected by shade as much as regular solar panel and still provided the majority of solar charging even if shaded a little. It would be enough to charge both your fridge and power bank. They are pricey but work great.
