My residential fridge draws 1.3 amps, 120 volts, when running which is nowhere close to all the time. My battery monitor says my batteries are down to 55% in 8 hours when not plugged into shore power. However, driving down the road they only drop to 90% so I have to believe that the truck hot wire is supplying 80% of the fridge draw. No DC to DC converter is used, just a straight connection.

Consider using a kill-a-watt meter from P3. Inexpensive and you can plug your fridge into it for a day or whatever duration you choose. It will give you actual power consumed. Go from there rather than guessing.

Sounds like great advice. Thank you.
