Not much for Winter camping. Head to Arizona for a month or so, but expect it to be warm in AZ.
This year in Sedona its been very cloudy and, well, cold! The living area is staying very comfortable with the furnace, but there's only one vent in the garage, so not enough heat to keep it comfortable to work on the computers.
So we headed to the Home Depot in Cottonwood and this "life smart" infared quartz heater.
Cost was $50. It comes with a battery operated remote for control, as well as the faceplate. Has a fan that moves the warm air around in the garage and makes it very comfortable to spend cold days at the computer!
Just thought I would share.
