Turn off the condensation eliminator on your Dometic refrigerator. It slightly warms the the frame between the freezer and refrigerator sections and draws a lot of 12 volt power.
This is really good advice. But you may not have an oem installed switch to shut down the door heater. My dometic does not have one. It is easy to install your own. The wire supplying power to the heater probably runs through the refrigerator light housing. It's the heavier of the two red wires. I installed a switch on my refrigerator several years ago and have never found it necessary to turn the heater on since.
