After our last move I had a problem getting the between-the-wheels chocks in on the curb side of the 5th wheel. I looked under the camper but, frankly, I didn’t know what to look at. When I mentioned it to my good friend Ron he looked under the camper and reported a broken spring. Today he came out, and with me mostly looking on and doing a bit of fetch and carry, replaced it. Apparently, this isn’t an indication that the other springs are on the verge of breaking, but I’m now carrying a spare, “just in case.”
September, 2015 follow up: Well, it was an indication that the other springs were on the verge of breaking. After another 3000 miles of towing a second spring broke. We used the spare to keep us moving, and then a couple of months later decided to upgrade all four springs to heaver springs. Once the upgrade is complete I hope we will be able to close this chapter of our adventure.
