Putting the scissor jacks up and down
I agree with what's been said, only I use a cheap corded Black and Decker drill to do mine. I plug an extension cord into the trailer's 110 outlet near the door, plug the drill into that, and then walk around the trailer doing the jacks. It probably takes less than a minute to do them. Just be careful when putting the jacks down to not try to level the trailer with them and, when taking them back up, to use a slower speed so as not to wrench the drill and your wrist when they've reached their traveling position!
You do know, don't you, that the trailer should be leveled first, before doing anything with the jacks!
