I too sleep in a RV during most of deer season and this does become a challenge during late NOV and DEC. We have our hose wrapped with Armacell pipe insulation and tape. I seriously doubt this helps very much, just a precautionary measure on our part. We let the water drip in the bathroom sink to keep the water flowing. That is about it other than we disconnect the water hose from the spigot when we leave for 2-3 days and the temps dip to 34 and below. Once disconnected, we "walk the hose" holding it up high over our head in an attempt to drain the majority of water in the hose so it will not freeze solid while we are away. Hope this helps, best of luck.
