One time putting the scissor jacks down and up on our last trailer was enough for me. Had the drill and socket before the next trip.
Funny thing is now I have a smaller trailer with much lower ground clearance. Bought an adapter at the dealership when I picked up the trailer. Only two single arm jacks (not sure what they're called) at the rear of the trailer. Much quicker and easier going up and down with the manual crank. So fast and easy it's not worth packing the drill.
