The OP described a situation where the air temps were expected to get down into the mid 20’s for 1 or 2 nights, with daytime temps in the 40’s. That is neither cold enough nor long enough to cause a problem. Not even close.
Water at 32*F needs to shed an awful lot of additional heat, 80 calories per gram, before it turns into ice at 32*F. That’s the same amount of heat it had to shed to go from 176*F to 32*F. That requires either very cold temperatures or a long time period.
I’ve spent many dozens of nights camping in that kind of weather with no problems. And my TT has no special cold-weather features. I would not give it a moment’s thought.
But, we’ve all got to find our own comfort level.
