Something pulling 10 amps from 12v

So my batteries came up flat a day or two ago and we pretty only boondock and we careful with our usage so this was very weird, we usually don't get below 12.2.

So I got my my multi meter out and I had a light go out about a week ago so I automatically assumed it had to do with that fuse and sure enough it was. It runs both slides, the fridge (which I have in gas without the defrost on), and that one light in the slide. I'm at a loss for what could be causing it.. Since it runs the fridge it's not like I can just pull it and deal with it later. Please help!
