So, just to close the story a bit...

It still does not make sense to me why the slide came half way in a few times.

What I did seem to find is that even though the lock pins were disengaging, I found that there was still voltage on the Unlock connector. The system is not sensing that the pins are being pulled.

To bring the slide in, I connected the Retract solenoid to the Unlock connector and it came right in.

When we put the slide back out at the next campsite, Kelly said that it made a clunking noise and jerked at the end of the extension. I'm going to try to spend some time looking at it again today to see what's going on.

Am I correct that the pin sensors are just hall effect sensors? Are there magnets on the ends of the pins? Does anyone know if there is a test point in the control panel where I can see the state of the sensor? Inside the controller, there is a molex type connector, from memory it was probably 9 pins, labelled "Rear Slide" or "Rear Room" that went into a cable bundle (ie not to the solenoids).
