As I mentioned above the pump and line leading from the pump to the point that line connects to the system will still have water in it. The pump head is metal and is unlikely to survive freezing. If your trailer has a filter from the fresh water tank just before the pump that has water in it. The faucets are metal and the cartridges are metal. Yes the newer trailers use plastic pipe and that is quite forgiving to freezing but the metal parts are not so forgiving.

It takes me about 10 mins. to pump less than a gallon of antifreeze into the system at a cost of less that $4.00. Your choice.
