I have a 25 foot Keystone Hornet that I have been dragging around for the last eight years. I have yet to find a site that I can not fit into. I use a small electric heater ( if hooked into power) to keep the cold off at night and the propane furnace in the mornings if it is still cold. The single battery that runs the fan will only last one night and it is not good practice to drain the battery. I have read and talked to people that have installed a Solar Panel and have had good luck in using it to keep batteries charged. I would be concerned about freezing the water tanks and lines if the storage area was not heated as I have no insolation in the storage area.
