You can re position the top portion of the jack (where the switches are) without moving the lower portion of the jack. I did this several years ago so I could tow my trailer with the gate down when I haul my motorcycle. Here are the steps;

Use blocks to hold up the tongue so here is no weight on the jack.
Pop out the two plugs on the sides of the top piece (where the switches are).
Remove the two bolts you will find there.
Lift off the top piece and suspend it being careful not stretch the wires to the switches. (I leaned it against my propane tanks.)
On mine there were two holes 90 degrees from the original holes. If yours do not have these, you will have to drill the holes.
Tap these holes to accept the original bolts. It is a good idea to put a rag down inside the tube to prevent the metal shavings from falling down into the jack tube.
Reinstall the top piece using these new holes. You may have to wiggle it to align with the top of the jack screw.
Test the jack.
