I think the heat strips are a good idea, but the way it was implemented on my RVP/Coleman heat pump it's close to useless, because it can't be controlled manually. When heat is called for by the thermostat the heat strip is turned on by an outside thermostat in the 35 to 40 degree range. Otherwise the heat pump runs. You probably can't exercise it at home because of this, which leads to the major problem: You're out camping, it's cold enough to kick on the heat strip, and it stinks like heck because it hasn't been run for a while. This is not when you want to open windows, so you just shut it off. I modified mine so I could manually select the heat strip and I like it. It's not nearly as noisy as the air conditioner, and unlike the heat pump, it throws out heat immediately instead of 5+ minutes after you turn it on.
