PRECAUTIONS WHEN OVERNIGHT IS BELOW FREEZING

We will be camping next weekend and the current weather froecast has the overnight lows at about 30 degrees. Is there any risk of freeze damage.? What precautions should be taken to prevent the possibilty of any damage?

  • We often boondock in the fall when the overnight temps will drop to 30 or high 20's. We set our thermostat on the furnace to 40, open the cupboard under the kitchen sink so that it benefits from the heater and we cozy up under blankets and sleeping bags zipped open. Early in the morning, I'll get up and start up the Heater Buddy, crack a window, and get back in bed for a little. We also always have either cinnamon rolls or biscuits for breakfast (or both), so that after I've finished baking and turn off the oven, I open the door and take advantage of the residual heat.
  • Hi,

    That's fine if the temps the next day migrate to above freezing. If they don't, eventually the sewer hose will clog with ice, then the gray water tank will fill, and you can guess the rest.

    Of course you have to have your gray tank valve open if you leave a faucet drip.

    Tom, a dripping faucet will keep your fresh hose from freezing, but the very slow trickle through the stinky will freeze it up. A 3" icycle. Want to wake up to a n overflowing gray tank and the rig flooded? How about the waste of the water? Conservation of resources is the responsibility of us all. It takes electricity to provide the water, then to treat it.
    Please use your fresh tank and pump, you will always have water without wasting or concern of freezing anything.

    Disconnect water hose and run from a full freshwater tank, rarely will 30 degree temps cause enough of a hard freeze to damage even rigs with water lines exposed to the elements as long as daytime temps rise above freezing.

    I won't blow my lines in storage unless the temps are going to be into the high 20's overnight with higher temps during the day. Stop and think how long it takes to make ice cubes in the freezer at zero and below!

    30? No worries while in use. Even if the water supply hose freezes it will thaw shortly once the sun is on it.

    Most RVs should be fine down to 25 or 20 but bring the hose in after you fill your tank about 3/4.

    I assume you have plenty of propane and plugged in.


    While above is true, what if it drops to 25? I would empty the water hose, just for precaution.

  • Your water hose TO the RV may freeze. But that is all. Noting on, or inside is in danger
