In the past month I have had both rear leaf springs break. The first broke while I was backing into my driveway to load the trailer, no harm done other than getting it repaired. The last time the other one broke while I was driving 60 mph on I40 in Memphis, this time it destroyed both tires when the frame dropped onto the tires. I don't carry any water in any of the holding tanks and am sure overloading wasn't a problem either time. Has anyone else experienced a problem with the cheap leaf springs? My trailer is three years old with less than 10,000 miles on it. Pete
