For several years I've thought about making 6-8 RV slips in one of the lower fields. The entrance to my driveway is 3 miles from Standing Indian Campground and there are literately 100's of RV's going by the main road every year. I'm confident I could gain favor with many of them in a short amount of time.
I've got access to free spring water, there is a pad mounted power transformer about 100' away, and installing a septic system to accommodate 6-8 motor homes shouldn't be that big of a deal. Not sure what the power consumption would come to but I can figure that out by doing a test on my own rig.
Also, it would be nice to have a place for my friends to park their rigs when they come out to visit.
EDIT: Here is a picture of the field where I would build it. Actually, the picture shows only half of the field. But I'm sure there is enough room to build a road around the field and make 6-8, 45' pull through pads.
