Ok everyone, we have found the issue and have at least temporary fixed it. My wife actually found the issue and fixed it after I was going crazy.
I removed the plywood covers over the wench / cables and I didn't see anything obvious. However, my wife noticed that the 4 cables were twisted together - I had assumed they were supposed to be that way. One of the cables had become "frayed" and a couple of strands were broken can causing them to all become twisted together. We untangled the 4 cables and put electrical tape around the problem cable to temporarily keep it from grabbing the others. I do plan to replace the cable but the important thing is that all 4 corners are returning back to the right height to close up the camper.
'I wanted to be sure others knew the "fix" as I had a hard time determining what it was and there is not much information on this issue on the internet.
Thank you all for your ideas. I do appreciate your replies.
