I've tried to find out how many amps the fridge uses while on LP, but the owner's manual doesn't say; it only lists amps when using 12 VDC to actually cool the unit. I'll bet it's pulling at least 1 amp. Does anybody know?
.9 amps in the normal mode and .4 with the hidden Climate Control switch "off" for my Dometic.
I have 3 group 27's and just completed a 6 day stint with NO hookups. I monitor the charge with a TriMetric monitor, phantom draw plus the fridge pulls me down 2% a day (that would be 6% on a single battery). I never got below 89% even with 2-3 hours of inverter driven TV/DSS. A two hour tow only got me from 89% up to 91%. A all day tow always got me to 100%.
A crappy solar panel added 2% back, keeping me topped off if I had a low usage day, otherwise I ran the Honda 2000i for an hour in the morning + one more in the pm to get to 100%.
