Airstream in below freezing weather...

I'm sorry but I have to disagree with the not exactly.

I think what you mean is If the area that you want to keep warm is insulated and gets some heat from the floor of the RV the wind will just accelerate the decrease in temperatue but can never make the pipes colder than the outside temperatue.

33 degree outside temperature even in a 100 mph wind will not freeze water.

If that is so, why do I consistently have a layer of white frost on the well insulated roof of my house on mornings when outside temps are as high as 35-40?

Because your roof is looking at outer space which is very, very, very cold. That's radiative heat transfer, which is different than the convective heat transfer which is being talked about here.
