Of course one has to keep in mind that a fridge drawing 4 Amps AC will pull about 40 Amps from the battery. 2 240 AH GCs would be able to supply that for a a little less than 120AH/40A = 3 Hours to the 50% discharge point.
(Less because 40 A discharge is far less than the 20 hour rate used to define the AH rating: 240AH/20Hours = 12 Amps)
If (when) our Norcold 1201 LRIM dies, the Samsung 197 will replace it. Probably powered with a pair of GC AGMs and a separate inverter and a pair of 130 Watt solar panels.
