[Western Traveler]

Last spring we camped at the Grand Canyon. We moved from a dry camp to a full hookup after the first few days. Most nights were mid to low 20's F. One night it was 12F. Mid 50's daytime. No winds. No problems incountered and nothing special done to our FW system. I checked it in the wee hours a few times. The furnace ran a reasonable amount of time actually less than we expected. As long as daytime temperatures got above freezing I would feel comfortable in doing the same thing in the future. Add wind and I am not so sure.
