Re: Residential Fridge battery run time
Our 2019 VanLeigh Vilano 320 has a Samsung residential fridge and Magnum 1k inverter. They draw approximately 160AHr per 24hr period. If you just have one standard lead-acid battery (85AHr) and only run it down to 50% before recharging (~12.0v, recommended if you want the battery to last very long), you will only get ~40AHr or 6hrs of running the refridgerator.
Of course there are several variables, while driving your truck will supply a few AHr (mine does ~3A) which will add to your time, if you run lights, furnace, etc you will eat up some of that capacity, if your battery is not new or in good condition it won't provide the full charge, etc. Bottom line, you really should have at least 2 standard batteries just for campground to campground with a residential fridge in my opinion, the equivalent of 4 FLAs for overnighting, and at least 6 for much boondocking.
I've added much larger batteries, and a whole-house inverter, to our 5er so that I can run everything and boondock for longer periods of time.
