I think that was us. We were living in the trailer during house remodel.
Tanks were fine but we do have tank heaters. We had lost our tankless water heater when we were out of town and the contractors knocked the trailer plug out. I think a faucet and the toilet valve thing. That was round one.
Then during the really cold weather I went to my sisters and my husband stayed in the trailer with bunks pulled up, every possible type of heater going (we were trying to keep house from freezing as well), propane freezing up so water lines frozen etc. it finally thawed. I’m not getting all that exact but my husband could sure fill you in on any damages. It was rough though.
