Your neighbor gave you good advise. If the hose does freeze and you go to move it, you might be buying a new on. Another trick is cover the hose along the ground with a tarp and grass. Some folks buy the foam insulation and run heat trace in side of it. My old coach I had to heat trace the waste valves or the would freeze solid. Was better then sitting out there with a hair dryer for a few hours trying to get to move.
