The answer is no. One night of freezing temps isn't a worry. It's when you get multiple days with wind that will freeze your pipes.
Care to share the physics behind that?
No, if it's cold enough to freeze, one night is enough. Wind can speed it up a bit but if it's only a couple degrees below freezing, it makes less impact than you might think (wind can be a real issue when in colder weather and you are relying on the heat from the furnace to keep everything thawed).
To the OP:
- How reliable is your weather forecast? If it's really 29F and it only drops below 32F for an hour or two, it probably won't be long enough to freeze but it's a **** shoot.
- If they are off or you are in a low spot where it gets down to 25F and holds for 3-4 hours, freezing is likely. The main tank probably not going to freeze as there is too much mass but lines and fittings don't have the same mass, so they can and will freeze more quickly.
If it's convenient to your house, you can just turn on the furnace and set it for something like 60F, that will bleed off enough heat that it should keep the lines from freezing while using negligible propane if you don't want to do a proper winterization.
One item to watch is the Black/Gray drain pipes. If they are exposed, heating the trailer won't do much for those, so it's best to drain those tanks fully, so there is nothing sitting in the exposed pipes.
