Winter RV'ing and water systems

We own (recently) a fairly new 1988 27' Fleetwood Tioga Class C and have been using it to go a few hundred miles to the Blue Ridge mountains during the winter. This has been great but, we've found that the fresh water drain tube and spigot tend to freeze if you walk by and say the word 'cold'. This isn't surprising considering where it's located. I've bought the spigot's by the handful but would like to know if there's a better version, not so easily damaged by cold weather. Also we found that the on board LPG tank has failed in that you can't add gas. We've changed the connection to one where we use the smaller tanks and purchased two of them. Has anyone else had similar problems with the LP valves failing in a way that prevents you from adding gas? Any advise would be welcome.

Hi, I'm not sure what you're referring to by 'fresh water drain tube and spigot.' If you can put a shut off valve inside the insulated portion of the RV and drain the line that is exposed to cold would probably be the best strategy to stop the frozen water spigot. The other direction is to enclose, insulate, and heat the space the water is going through. Insulation alone won't really help unless heat is introduced to the area also. In many RV's the wet bay, with all tanks, pumps, and drains are in a space that has a hot air duct from the furnace to prevent freezing. It's enough to keep above 32 but not enough to heat the water in the fresh water tank.

Thanks for the post. The tube and drain valve extend below the bottom of the camper under the fresh water tank and the heated water tank. There is a double floor on the camper which prevents easy access to the hose from the inside. I think that I will need to put an access door on the inside to add another valve to be used in the winter. (under the table) We brought the RV and are sharing its use, and the expenses, with our son and daughter both of who are living very close with their families. Because of this we want to keep things as simple as possible to maintain, no matter what the season. Thanks again...

Another option is to drain all water, winterize the system & pour a gallon or so of RV antifreeze into the black & grey tank. When camping bring a few gallons of water to flush the toilet & do dishes. That way you never have to worry about keeping the heat on when it's not in use. We always seem to end up in Canada for Christmas and this is how prevent freeze-up while traveling.

If you are camping where electricity is available, you might be able to use heat tape on the exposed water lines to prevent freezing.
