I got a call from my brother yesterday evening. He was driving up the interstate last night towards his camping spot north of Phoenix, glanced in his rearview mirror and saw his trailer was at a 45 degree angle to his truck.

Wind had caught it, and ended up tearing off about a quarter of the rear wall. Total loss, along with a substantial loss of his possessions. Fortunately no one behind him was hit by debris.

The trailer wasn't expensive, but it is basically his home, so pretty serious stuff.
