Spent this past weekend in the 19' camping at an unserviced site in Jasper National Park. Most of the weekend was cloudy with only a few sunny periods. We had pretty heavy morning and evening usage of the electrical including water pump, furnace (on-off all night), Max-fan, chargers for IPods, Television (watched a movie), and interior lights. Even with all of this, the dual 6V batteries with solar charger performed very well and I don't recall seeing the battery charge level drop below about 80 percent. I cannot say enough how happy we are with this system.
Despite the rain, I still managed to get some good whitewater paddling in on the Athabasca River with my son.
