Stupid is as stupid does
Use electric winches on each of the jacks to make them powered. You could also then possibly power them separate to help level when parked.
My buddy Nick suggested something very similar, but hydraulic. This company specifically: http://www.thebigfootleveler.com/
I ordered sprockets, chain and pillow blocks just an hour ago. $100 invested. Thanks to aczlan for the surplus center link. I've got a lathe and a mill, so I'll make the hubs and pins needed to make this chain system work, then probably just reuse this current cross-bar for the upper.
In the next week or so, I'll get this area cleaned out and start planning for the genset mounting.
