I've just ordered a new Coleman Polar Cub air conditioner for our UHaul 16" trailer. It should be arriving next week, so I've got a couple questions:
1. How complex is the wiring involved in setting up the AC? Does it need its own circuit breaker? Can two men handle the installation (it weighs about 94 lbs.)?
2. How well does the heating strip in the indoor control unit help to heat a trailer? Will I still need another furnace or small heater?
As the biggest energy user in your trailer, the AC should be on its own circuit. I just paid to have a Coleman installed - they charged me one hour labor and it was worth it. The local RV shop used a forklift to place the AC on top of the trailer. My back appreciated that. They also knew exactly how to configure the wiring.
I had a heat strip on a Polar Cub in my former Casita
trailer. I was living in Alaska at the time and it wasn't usually adequate. You live far enough north for weather that will also be too cold for the heat strip, unless you only camp in the summer. The Cub also doesn't have a very precise thermostat so you have to fuss with it all the time. Many electric space heaters work better than a Coleman heat strip and are quieter. I didn't bother to get a heat strip on my recent AC purchase. I would rather use the furnace or a space heater, as needed. The good news: the Polar Cub will be a great air conditioner for the size trailer you have! It also operates well on a 2000 W generator
if you are inclined to use one. Most other RV AC units require a larger, noisier generator
. However, you can't run the heat strip on a 2000 W generator
. That is where a nice gas furnace really is essential - boondocking
in cold weather.
