Also, the Cheap Heat system is supposedly more economical to run. What they advertise is 100% of the energy used in the resistance coils to produce heat that is transferred to the heat ducts. With propane, as much as 40% of the energy is blown out through the exhaust duct. To me, if I were going to camp in cold weather for an extended period of time, the Cheap Heat system would be a necessity.
We were in North Carolina for Thanksgiving last year and the temps went into the single digits at night. At the time we had a 40' 5th wheel and we went thru a 30 lb tank of propane in 5 days.
