freezing temps.

Trying to keep my options open as late in the year as I can and wonder at what temp. do you really need to be concerned about plumbing freezing on a 5th wheel outdoors.?

i installed remote indicating sensors in my water tank and water service compartments.
i found that a 100w light bulb in the compartments will keep the compartments above freezing down to about 22 degrees outside temp.
i use a 1500w cube heater with thermostat inside my moho.
incandescent light bulbs are getting hard to find.

When we owned trailers I never had a freezing problem following this personal rule for outdoor storage; when early morning lows stay at/above 28 and afternoon highs reach the 50's water lines will not freeze, because residual heat in the trailer somewhat offsets the low temperatures.

The outside water hose will freeze first before anything else, so if overnight temps will be below freezing, then fill the fresh water tank, disconnect the water supply and use the 12v pump.

I have camped for several days with temps in the low 20s at night and never getting above freezing during the day w/o problems. And that is with heating the camper with electric heaters rather than the furnace, so just radiant heat thru the floor will keep the tanks from freezing. However if your black/grey tank valves are exposed, they will freeze. I did make one mistake, left the galley tank valve open and draining thru a garden hose which froze and then liquid at the valve also froze. Didn't damage the valve or pipe, but busted the sewer cap tabs.

In my opinion, the first thing that should freeze (and therefore needing protection) is the fresh water pickup tube because of it's location and small size. And once it freezes, you have no usable water supply. But I've never actually had it freeze.
