Residential fridge

That is the downer to residential fridges! If you stay put for long periods, and only move occasionally then they are great! Now, if your on the move a lot, your going to have to become an “expert” on batteries, and inverters. Starting with the alternators, yes plural. In your truck. Did your rig come with an inverter? What size is it, does it power more than the fridge? Perhaps, you need to upgrade it, or add one if not present? What is the amp rating on your house batteries? Typically, the factory ships their rigs without batteries, which are provided by the dealer at the time of sale. Again, they typically install the smallest, cheapest batteries they can get away with providing! Some people install a couple of 6 volt golf cart batteries, to ensure they are providing enough amps to run things! That would then require, looking at your charging systems, both in the trailer, and in your truck, keeping the batteries charged! Yep a residential fridge can become an expensive option, if you outfit your truck and rig to support it! Good luck!
