No doubt about it. Refrigerators use a lot of electricity.
The Kill-a-watt will tell you how much electricity the refridge uses, which you can use to calculate how fast your batteries will drain.
To get more battery storage, I changed my 4-6v batteries to 4-12v blue top optimas.
This about doubled my stored power, and length of time that I can run my coach off the inverter. You might want to consider this if you plan on a lot of boondocking.
Take care
Rick
