The heat strip is just a resistive loop. If you're not worried about running the fan, let the A/C run. It will keep the air circulating even if it's not the primary heat source, and the trailer will be more comfortable. Besides, the heat strip will contribute *something.*
I've found that the heat strip is good for about a thirty degree difference only. I set the furnace thermostat for the temperature that I really want to wake up to, but in the mild winter climate here, I usually find that the heater outlet isn't even warm when I wake up.
2toomany, the furnace is the primary heat in the trailer - it's not the backup. Think of the heat strip as casual use heat. Don't plan on going through a cold night on it alone.
