I saw this on the national news last night. DW and I were mortified. Our "tin can" doesn't stand a chance even in the mildest tornado. Luckily we don't have a lot of tornadoes down here either, but microbursts from extremely strong and sudden thunderstorms are quite common and often come with little to no warning.
One of our last cold fronts came thorough while I was towing the trailer back to storage, had sustained 40 mph cross-wind for part of the journey and I could see my trailer leaning over pretty far. It was not a comforting feeling to say the least, luckily I didn't have sway problems and I got out of it quick.
