Our new Mobile Suites came equipped with two 6 volt batteries and a 1000 watt inverter.

Looking at a brochure, it appears that 5er has at least a 22 cu ft side by side refrigerator with bottom freezer. Very nice but those can draw up to 20A !

I also noticed that the manufacturer offer an upgrade inverter with 4 batteries ! I hope you won big at the casino because you will be spend your winnings on this upgrade !

I got kicked at the casino, but that's beside the point. It is a 20 cu ft fridge and if I read right is supposed to draw on 5 amps. The furnace was on and water heater on propane. The inverter is dedicated exclusively to the fridge, not to the tv or any other a.c. appliance, or so we were told.

That 5A would be at 120V. So about 600 watts. At 12V, that's 50 amps. Unless you have LED lighting, each fixture will likely draw 1-2 amps. The furnace is going to draw a few amps when running. Your 2 batteries are probably around 200 amp-hours. Way before the batteries are fully discharged, their voltage under load is likely going to drop below the inverter's minimum input voltage, so it will shut off. That's assuming they were fully charged to begin with, and that won't happen driving down the road or with the common WFCO converter most manufacturers use.
