I would put the power settings to M. High is only good when the vehicle is running ie 13 plus volts. Low is good for dedicated battery. We also now have small battery packs you can use in your rig that will run the fridge for 8 hrs at a time and can be used as a pass though or in conjunction with a vehicle battery.
Once I am closer to coming back to the US, I will be contacting you for one. I’m currently stationed in Germany but will be coming back end of June. Plan to buy my vehicle in Baltimore and take my time to drive down to Arkansas for my next duty station. Could I have it shipped to a hotel? Thank youYes they are
