UPG 250 amp hour agm batteries
I just finished up my residential refer install with inverter. I have two 75 amp hour batteries that will suffice for now. But this worked so great and I had so much fun with it, I started searching ...

Crosscheck, it's not that "all electric fridges don't work unless you are hooked up". It's that 120V fridge won't work unless you have a lot of batteries and means to charge them, or you are hooked up.
Yours is 7.5 cu.ft 12V, and even though it's big for a 12V model, it's an equivalent of a small office fridge - not a residential fridge. With an added bonus of not using an inverter, its energy efficiency is boosted by another 10-15%. The net result is 50-70 AH in 24 hours compared to 90-110 AH of residential unit. This comes at a steep price, 4-5 times higher than a bigger volume residential unit from big box stores. For a longterm boondocking away from propane sources 12V fridge and solar is the way to go, yes. 7.5 cu.ft with 300W looks underpowered for cloudy locations like BC. Your batteries will stay undercharged, dropping to 50% or below and never reaching 100% (you might think it's 100, while it's not), without a generator. But it will work.
