Bedroom slide out

When we got our RV we saw the slide-out motor  under the RV and were briefed on how to manually do the one hidden under the bed.  The problem is I have never actually manually gone through the steps.  So this spring I want to go through the motions on both.

Above is looking to the head of the bed and below is at the foot of the beed showing the electric motor.

I also found I have not picked up an extra slide out fuse so I will do that over the next month.  I have two slides so I should pick up two.
