Below freezing camping

[HappilyLost]

This week we plan to go on our last trip of the season (for a week) and one of the nights the temps will get to 27. All other nights it’ll be above 32. My question is without a heated underbelly will I be ok with water in the lines if I am running the furnace all night? I’ll be using the fresh tank and not city hookups. Any insight appreciated

If furnace ducting runs under the floor of the camper and is designed for heat loss to keep the area warm, you should be ok.

If you have the enclosed underbelly then TranceX2 is correct. If the underbelly is open then it is not heated by the floor ducts from the furnace. If you have the enclosed underbelly you may also have tank heaters.

Most trailers are made with the water lines above the floor, with the heat on the lines should be fine.

Agreed. I don't see any problem.

OP says he will be using the FW tank which is below the floor and the supply line from the tank to the pump will be the first to freeze.


My lines are under the floor in the insulation.

I found after going out last weekend in freezing temps that the same heat dams, plugs pad or whatever you want to call them that I use to improve the efficiency of my AC make a significant difference in the heating efficiency as well. I block all three of my roof vents and the skylight over the shower with foam blocks. I must have done it about 1 am last weekend and within an hour the TT felt warmer and the cycling interval of both furnace and electric heater had changed. As far as the water lines, you can leave the affected cabinet doors open slightly as well

I would moly turn the pump “ON” when actually needing to use on board water.

That way, if any lines were to freeze or split through the night, there’d be no more water leaking out than what’s available nearby, instead of the pump seeing the split as a demand for water, and start the pump running.
