I was able to find an open box special on Ebay and found a good deal.
The instructions for changing are somewhat vague so I found a way that made it pretty easy. After I removed the old spring installed the new one, at which point I was suppose to rotate the spring and then insert keeper screws, which while under torsion would have been a chore. Instead, I put the new spring in, installed the keeper screws, and then took the awning arm off the side of the motor home and then used it as a lever to rotate the spring (17 times from memory) and then just reattached the arm. I did have the advantage of being able to work out the bucket of my tractor. It would have been harder on a ladder.
