curran4444, First you need to determine if it's a electric/hydraulic slide motor or electric gear drive under the coach. If it's hydraulic, look on the end of the drive motor (front storage compartment) and you will see a round sticker. Peel off this sticker and using a good cordless drill and a hex drive bit, run the motor to extend or retract the slide. If it's electric gear driven, you should be able to find a shaft under the slide with a slotted piece on the end. Find the tool which should have been noted when you picked up the trailer, and crank the slide in or out as needed. Is the reason for your question just in case you need it or do you have an existing problem? If you have an existing problem, explain it and someone may be able to help more. Good Luck.
