Buddy and I loaded up our RZR's and wives and went to Roper Lake State Park outside of Safford AZ for a week. We awoke to a light dusting of snow on New Year's Day and freezing temps. We had the Voltage heater set to 65 at night to keep the basement warm. During the day we used an electric heater to keep the people warm. The garage was terribly cold inside.
Then the larger snow storm came a day later and dropped about 4 inches of snow on us. It got down to 17 by the next morning but we were still toasty warm. In the week we were there we almost went through one bottle of propane. Having the electric heat saves on the propane.
Daytime temps melted much of the snow in camp over the next couple of days and turned the place into mud, which our RZR's loved. We made a RZR trip up Mt. Graham on an un-plowed highway with about six inches of snow on it and had a ball.
Roper Lake is a real nice state park. The gravel campsites are long and wide and only in need of sewer hookups. Each campsite has a picnic table located on a concrete slab under a large wooden canopy. Most of the campers in our area left soon after the snow arrived.
In five years of ownership, this was the coldest trip we've made with the Voltage and it performed flawlessly. And the water lines and tanks didn't freeze
