It depends on the fridge (and its installation). Some have fans, some don't, for one thing.
If memory serves my fridge (whcih is a similar Dometic model) uses about 0.5A when the burner is operating, and maybe 0.2A when it is not. That works out to somewhere around 5-10 Ah per day. (That is without the "climate control" switch being on, which operates a little heating element around the door seals in case of excess condensation there; I never use it.)
If the fridge is in a slide, there are very often fans used in the installation that will consume additional power.
