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!

ONE alternator in my 15 RAM, two 6V batteries and one 1,000 watt inverter in RV. ALWAYS arrive with temps the same as when I left even on my 33 hour trip mentioned above.

One time I did arrive with temps up. Reason was the batteries were on their last leg. Trip to Costco and all has been well since.

That may well be true! There are options for two alternators on these vehicles! I was expressing to the OP what he “MIGHT” encounter going down this road. There are many variables, and you can not post on a particular situation and expect that to cover all alternatives! Congratulations on YOUR PARTICULAR situation, but it does not cover all situations. Not to mention all the alternative’s and allow the OP to think his situation and yours are identical is doing him a diservice!
