You may or may not have a problem. The heat pumps/AC systems on these RV's use a small coil, compared to a residential unit. It's basically the same coil they use for strictly cooling units on RV's, but now also use it for extracting heat as well. Because of that, the heat pump doesn't really "heat" very good at anything below 45 degrees outside air temp. Any OSA temp below that, and there just isn't enough "heat" in the air to work well. Getting down around 32 degrees and the coil may very well "freeze up" due to being "overworked" and not enough surface area. I did a test on ours, and pretty much anything below 45 degrees OSA and the pump couldn't really keep up. When OSA dropped to 40 degrees it was a losing battle. Then it's time to bring on the furnace and get the temps back up. Anything above 45 OSA, and the heat pump part works really well.
