Gonna get pretty chilly down chucktown way tonight. I would imagine Irmo will be a little colder....You should notice a difference in being plugged in.....if nothing else, the heat will be warm inside the cab pretty quickly. If you decide to plug it in pretty regularly, a timer set for about 2 and half hours before you need to start it will keep you from running the 1500 watt heater all the time....Let me know how it goes.....Dave
