I was in Death Valley last week on a 7 day trip and on day 4 all four leaves of my trailer springs broke in half. They broke right in the middle where that center bolt goes through. I didn't loose the axle, but the trailer almost tipped over and it bent my hitch a little. I was able to find a pair of springs which have 5 leaves and look more stout. Now I at least have one spare for future trips.
