kayteg1...that's a combo heel bar/spud bar. But it will work.
Think of what a Ironworker uses 30 floors up to align holes in I-beams, without the open end wrench on one end. For the visual just eliminate the hooked end in Kaytegs pic.
You should be able to find spud bars/alignment pins in different sizes.

If you have room to get the alignment pin in both holes you should be able to move the camper enough to drop the bolt in, if the jacks are on a piece of plywood or a wide board.
