When I moved from Texas (
) to Florida in the fall of 2011, I put my computerized machine in a U-Pac, pod like, trailer. It did fine, but then again it wasn't as hot as Florida is in the spring, but had a lot of days that were hot. I did have to store it for a month in Jacksonville in December. Not cold weather, but not 90's. Again, it did fine. I have been sewing on it on a regular basis since then.
