Many answers and it depends how cold, for how long, and what kind of chances you're willing to take. Plumbing damage from freezing can be expensive and time consuming to fix. I had to replace a toilet once even though I had blown out everything with air.
If I were in your situation I would consider keeping the trailer warm enough with some supplemental heat to reduce the chances of damage. That will also keep the humidity down and help keep everything fresh. If you keep the interior at 45 degrees you should be good down to 20 degrees outside temps as long as the trailer is out of the wind. No guarantees, but that's what I would do
