Why do they put heat pumps in trailers?

yes, over time . . . probably around May or June for someone in your region

I avoid using the heat pump in our trailer. I find the noise to be intolerable.
I hated the air to air heat pump we had in our house. We have a geothermal heat pump in the house now and I love it. Guess that won't work in a trailer

From Airstream's specs, it looks like the Sports don't come with a heat pump (at least not standard.) If that's the case, I'd guess "Opt Heat" would be a heat strip in the AC unit. I thought the newest version of the thermostat says "HP" for Heat Pump and "HS" for Heat Strip...

Thanks. If it is a heat strip, it is pretty wimpy. I'll just throw a small electric space heater in my "go box". I have one about the size of a cube box of Kleenix that works really well.
