Pretty cool video about weight distribution. I've had it happen to me within 2 miles of home going under 45MPH hauling a skidsteer, I thought I'm close to home it won't happen to me. Luckily was able to stop before wrecking. Saw a guy in a ditch after leaving an auction once because he had to much weight on the back of the trailer. Watch this 13 second video, pretty neat.
