If you have searched this on the internet you will already be aware that there are lots of complicated methods of keeping your rv water hose from freezing. Some people say that using electrical tape wrapped around the hose followed by insulation foam is the best method, whereas others prefer using a heat cable in the same power supply as the hose. All of these methods will work but the easiest option if your RV is exposed to the cold, is to buy a heated water hose which will fix this problem for you in a matter of minutes. This might be a more expensive option but it’s much quicker and easier, giving you more time to enjoy your trip.
