The big slide has an opening on the curb side, If you open the cover and look you will see a big bolt, If some one were to open the slide you would see that bolt turn. There should be a manualcrank you use to do it manualy laying some where in your camper. The other I think you go under the bed for the bolt ?
On my 2011 30SKP there is a hole in each slide. Take your manual crank and thread it through the hole in the slide opposite to the one that is stuck. Position it on the metal rod with the pin through it. Crank clockwise to close the slide, counter clockwise to open it.
