Got into Tucson about 3:15 yesterday. Staying at Catalina State Park. After finding a place to set up, went to dump the tanks. While doing so, it was snowing, temp 37-degrees. No sticking, but cold. I checked the temp at 9:15 last night, it was 25-degrees. Does anyone know what the burn rate for propane is with the furnace? Here's hopeing it will be a bit warmer in Quartzsite in a few weeks.
