Dometic compressor fridge?

We bought an Isotherm compressor fridge from West Marine in Buffalo last year. Chose Isotherm after many hours of researching online. Best investment I've ever made in the camper. I think it was about $1000. Not sure how much 12v electricity it uses, my solar charges the batteries during the day and the fridge runs off the batteries at night. Seems like the batteries end up at 90-95% after running the fridge overnight. I have 250ah of batteries.

Can't believe I suffered with that ammonia fridge for all those years.
