With only 2 batteries you are going to be in for disappointment for any camping without shore-power. Especially with a 10 c.f. unit.
You are probably very right, but I have found another poster here that has had success using two batteries.
Here is why I think that it might work (check my math):
According to the yellow sticker, this Fridge uses 312kw/yr.
That is 312,000 watts per year.
That is 854.7 watts per day.
or 35.6 watts per hour
or .29 amps per hour (remember this thing isn't running all the time)
or 2.9 amp per hour at 12 volts.
One of those 12V overhead lights will suck down that much juice.
Running it for 10 hours over night should use 30 amp hours. My pair of batteries are rated at 245 amp hours or 123 usable amp hours. I think that I could make it work.
I'll find out soon enough, I'm sure:B
I have a 7.5cuft fridge that uses 4.6A when cycling on 12V.
You say 2.9A for a 10cuft unit. Better check your figures.
