On our previous coach (2008 Monaco Dynasty), we had three hydraulic slides and one electric (the electric slide was the one with the bed attached).
Once, the control board connections vibrated loose and none of the slides would move. I found the control board at the ceiling of one of the bays behind a panel. I pushed the connectors in and all was well (had to do that a couple of times over the years).
Then another time, the living room slide on the driver's side got quirked somehow. When I was retracting the slide, I noticed that the bottom rear of the slide was kind of sticking, the top was moving fine. So, I stopped the slide before it got more 'quirked'. It was sticking out about 4-5 inches.
I drove it like that to service 65 miles away. The tech told me it was good that I stopped it as a bracket would have bent if I had forced it (which would have cost more repairing it). All it needed was an adjustment and all was fine again. He told me to have the slides checked once a year. I never read that in any of the manuals.
So, in 7.5 yrs. of owning that coach, the slides just had a couple of issues.
On the new coach (4 electric slides), I got a message on the dash readout that said 'you must put transmission in park to open slides'. The sensor was set to a very sensitive setting. As we were going around a curve and the coach would lean slightly, the message would appear. I took it in for service and they adjusted the sensor and all was well, no other problems.
