Kelly,
My system could charge the two GC-2 batteries to full charge (when they are relatively fresh) from about 80% to 100% in 5 - 6 hours, even before I added the second 55 watt panel. This is in the desert sun in the Southwest.
We are pretty conservative with our power use and only use the lights we need (LEDs) at night, sometimes the TV/DVD combo, and computers off of our 750 watt H.F. inverter. The fridge is a 3-way, so it barely uses any 12 volt power. I doubt that a 50 watt panel will do the trick for you unless you are REALLY stingy with the power use. We sometimes run the pump, as needed, and sometimes even the furnace, but only to take the chill off first thing in the morning.
Last Summer, we dry camped at the North Rim of the Grand Canyon for five nights in a mostly shaded spot, and although we used the Onan a few times, briefly, to heat water, we never went below about 78% on the batteries as measured by the Trimetric meter.
