RV Fridge with No Temperature Controls

OK, so the fridge is finally installed but now there is a new problem. It seems to be draining my precious 12V power. I am full-timing off the grid so this is big problem. My old Dometic certainly didn't do that, but this one has fancy temperature controls which may be the problem. I have also noticed that it's not uncommon to hear it re-lighting the pilot light which apparently uses a lot of power. I know this because the other day my battery was low and the check light came on in front of the fridge; no matter how many times i pressed the power button on and off I couldn't clear it. All the other appliances worked, although the lights were kind of dim. Once I started the engine I managed the clear the check light.

Sigh. Are these fancy new fridges just impractical versions of the models? Has anyone else had this problem?
