Well, like I said, don't cater for the best of times. In summer in Tasmania, it's getting light at 5am and the sun sets around 9pm. Usable sunlight would be from about 8am to 6pm - 10 hours at 8 amps is a lot.
During the lower-light times the panels all still produce power, but obviously not as much. Where you have 5 hours in winter time of decent full sunlight (which is what they rate the panels for) you might also have another 4-5 hours of light varying from "Christ, I didn't see that log in the shadows and I tripped over it" to "well I can see, but I won't get sunburnt in this!".
During those lower-light levels, don't count on full production. I'd quarter it and rely on that figure - so for a winter day, with (say) 5 hours of lower light levels, you end up with 5*(8/4) = 10A produced during that entire time.
And yes your fridge probably won't draw 4A at all. I know my Engel is rated to draw 4A but only pulls 1.5A. I sized my battery as if it WAS drawing 4A - spare capacity is good.
A cloudy day will change the figures. So will parking in shade. One of the drawbacks of solar panels is that to get the optimum amount of power, you need them out in the brightest light - and that's generally turns whatever you're sitting inside into a mobile bakehouse.
I do NOT think you're making a mistake. You may not run much more than the fridge without losing a little power each day - which is why I mentioned the lighting, but that panel is not bad, especially for the price.
