Here is more info about the Costco Solar set up than you probably care to know:

And.. yes, your problem is the fridge
. 12v fridges can suck the life out of a battery in no time flat. Best to look for a cooling alternative. Propane
is best if you have it.
That being said, I use the Coleman/Costco set up @ v45 watts and an auxiluary 15 watt panel...and have changed all my lighting
to "green" stuff.. low low current draw items like Cold Cathodes and LEDs.
I want for power no more. Seriously, it's just not something I worry about anymore. I have run several times at strickly solar for many many days on end, with full use of what I have in the trailer, including TV and DVD.
My genset stays home, where it is used the most anyway.
