I found one after many yrs. looking for the ideal mini heater for just the waking hours and/or watching TV. We camp mostly in state park and during the winter operate a 1500 watt electric heater evenings. Have tried to run two 1500 watt heaters but breaker is constantly tripping because of current overload. Well the solution just appeared from Mr. Heater a portable propane heater that utilizes the small 16 oz Coleman propane bottles. the heater is designed and certified to operate inside. It's perfect it will run for nearly 6 hours on low and approx. 3 1/2 hrs on high. I operate it on low setting and along with the 1500 watt electric heater the camper is very warm even with temp in the 20 degree range. I do not run the camper propane furance because the it use requires refilling to often. This little heater from Mr. Heater is ideal for use during the evenings. I would not leave it running while sleeping but otherwise it is a perfect choice. Simply replace the little propane bottle and keep going. I think the Mr. Heater just recently hit the market. I purchased at Lowes but have seen it at Cabela/Bass Pro as well.
