There are other things in the trailer that don't like being kept below freezing. Plastics turn to glass and condensation or other moisture turns to ice. Plastics get hard and shrink which causes stresses and since the plastic is now glass instead of plastic, it cracks.
While I suspect it would avoid a repeat incident, it might be impractical to maintain a +70F differential. I suspect that even at 0F the floor wouldn't have had the same problem, though, so it shouldn't be necessary to keep it above freezing, just above oh-my-lord-that's-cold
Those sorts of temperatures put my kvetching about Texas summers into perspective... but I still look forward to a time when I can leave Texas for most of the summer!
