My dual fuel refrig in my 5th wheel doesn't keep things cool enough. I am going to replace it. Dry camping is a seldom done thing; we mostly travel, stopping in RV parks with elec. and water. I want to put a battery and inverter into my refrigerator swap out, so that the refrigerator will stay cold while we are on the road.
If you are on shore power overnight and you NEVER open the door to the refrigerator until you are plugged back into shore power and you are on the road for less than 10 hours per day, you really do not need an inverter.
Now that I said it, I would get a name brand 2000/4000 pure sine wave inverter and TWO 6V golf cart batteries.
Samlex makes a nice inverter/charger. I like it because of it simple wiring. Get rid of your old converter
(keep the DC distribution panel and wire it directly to you house battery bank). The shore power connects to the inverter/charger and there is a built in transfer switch so you use shore power when connected and inverter power when not connect WITHOUT OUT HAVING ANYTHING TO SWITCH ! It will also accommodate a generator and input from solar panels.
You really should have your house battery bank hooked to your tow vehicle battery via a DC-DC charge. Read this regarding charging a house battery from a vehicle alternator.
DC-DC battery chargingEDIT :
Samlex 1200W/3600W inverter/charger (no separate generator input; plug the generator into the shore power plug)
