Sub zero Temps cause damage?
Went to the storage lot today to check on my 2002 Winnebago Brave and run the generator. During the week we had temperatures of -15 degrees and several days where the high for the day stayed below zero. Today the high was 45. I was horrified to find the vinyl flooring in the bath was split from the shower across to the toilet. Just like a ragged crack in ice. There is no sign of water damage under it. Plywood under floor looks fine. I couldn't find any other damage. Could the cold do this?
