First, I agree with everyone trying to find a way to keep your current spot.
Second, I think I'd adapt a tire skate:
TireSkates for moving that car, truck or boat around by hand.
to work on the jacks, not the tires. Put the jacks down on to the skates, push the motorhome (winch it with a cable attached to a skate?), and then jacks come up.
I'd question whether the jacks are torsionally stiff enough for lateral pushing of the motorhome itself. And, engine running would have the power steering on so that there isn't as much effort to twist the front tires...but a thin teflon square under the front tires would keep them from gripping the asphalt, it's like portable plastic ice when wet.
