As the subject says, the fridge motor turns off and on all the time when the batteries are below 12.3. Did the fix about a month ago and waited to see the results before posting, its very simple.
1. Remove fridge, unplug red and black electrical wire harness,
2. Remove rear bunk control panel (my have two 12v lighter plugs).
3. Splice wires from the fridge plug to the 12 volt lighter plug.
4. Reinstall everything and done.
Now my voltage don't drop below 12.4 overnight parking without truck running, with watching TV maybe a hr or two before going to bed.
