Something additional to consider in addition to John's excellent advice.....
The slide motors are the heaviest current draw on your 12vdc electrical system of anything in your rig. Running them on a less than fully charged battery without shoreline is a good way to discharge the battery too much. My Cougar has four slides. Running them all in or out uses up a lot of juice. I leave the pigtail plugged into the truck with it running and on high idle and the shoreline disconnected when setting up or knocking down. If I am at home, the batteries are almost always at peak and the rig shorelined so I don't worry about running the slides in or out.
I do admit to having the advantage of a dual battery diesel truck with relay controlled charge line and the high idle option engaged. The 25 amps of juice available on the charge line is comforting, especially running that last slide in or out.
