You're Full hookup requirement is pretty much gonna force you to be among lots of campers parked close to u'r rig. If you'd rather 'Camp' with water only, our favorite place in S.Utah is on Route 12 north of Bryce. Its a little State pk. CG called Calf's Creek. Its nestled at the bottom of the canyon along a crystal clear trout stream. Altho the entrance sign recommends 25' on shorter RV's, We've gotten into sites with our old 34' Class 'A'several times. Its 1st come 1st serve. Our 2nd best favorite is a Nat'l forest CG just west of Bryce on Rt.12 called Red Canyon. Its very near the natural tunnel u drive thru. Again water only but big rig friendly. Sites are spaced well apart with plenty of foliage for privacy.
