With a rig your size I would look into area #4 which has the larger sites.
Area #4 has water and electric, look into sites 141 to 164 but stay away from site 148.
Area #1 has water,electric and sewer, all the sites are good, but try for the outside perimeter first.
Area #2 has water and electric, but try for the upper sites, 1-4, 10-12, 21, 22,
30, 31, 42-44, 53-56.
Good Luck
