Stuck in the bush . Slide out will not come in on RH side

Is the motor turning? If not, is there a separate fuse for the slide motor? (both my current and last rig had this). If so, check that fuse.

If it is turning, the odds are good that a shear-pin, connecting the motor to the drive, has sheared.

Can you hand-crank it out? (you might have to hand-crank it back in too, so only a bit, then check to see if you can crank it back)
