My wife and I are heading out this coming weekend and temps are supposed to be in the mid/upper 50s during the day, with the lows dropping into the upper 20s. The trailer is not yet winterized, but currently sitting empty of all water and all valves open just in case we've hit a cold spell. My question - if we're going to be running the furnace/space heater this weekend regularly keeping the interior toasty, would filling it up with water be an issue in the colder temps? I'm thinking not, but my main concern would be the outside shower on the outside wall (which we never use).
We have one more trip after this weekend (the following weekend), of which all signs/extended forecasts currently point to above freezing temps after this weekend.
