Our heat pump isn’t effective at all under 40 degrees as others have noted. The newer furnace in these units are designed to operate going down the road and after doing that in below freezing weather many times on different rv’s I’ve not found or heard of one that was designed to shut off when moving so I think something else is going on with yours. Also, I’d check those vents everywhere possible for narrowing or blockage on the flow path. I’ve heard of folks finding that more than once. It’s aggravating, but luck to you getting it dealt with!
