Mar 20, 2018A good rule of thumb is the lower the temperature the faster water will freeze. Water starts to freeze at 32F, but it takes hours of exposure at that temperature for the pipes to get to the point of bursting. If you're talking about an overnight dip into -32 or high 20's then you'll probably be fine. The heat inside of the trailer will keep internal pipes from freezing. As long as the temps aren't below freezing for long periods of time, external pipes should fair well.
A couple of months back we did 3 nights in -10F. The only real problem we ran into was that the regulator froze up one evening, but a hairdryer fixed that. The low points did freeze, but luckily none split open.
