My manual crank has a tube with a pin thru it, the same as you describe and the manual crank handle they supplied to use with it has a hollow end with a slot to accept the pin, did you not get a crank handle?
Did you check fuses? Is your battery fully charged, try it connected to your TV with engine running, do your other slides work? just some ideas.
My slide gears etc came bone dry I sprayed them liberally with lithium grease, hope that was the right stuff same with the tv antenna is was so stiff, I had to spray all the locks too half the keys would not turn the locks, basic stuff that FR or RVW should have done before I picked it up.
