Here is the video that explains what I was describing.
I also had this happen when retracting. It appears to just stop when rolling up. At the time I was all packed up and ready to head out. I would wait a few seconds and it would try and retract a little more. Motor is completely silent when it stops. No errors anywhere else. I actually managed to roll the entire thing up in the wrong direction...
pjciii, good reminder about the 7/16 nut driver or socket. I figured that if it ever happened I could hopefully find someone in the RV park with a ladder.
