I camped twice at Utah Lake just for shakedown runs, I hooked up to electric and water to make sure everything worked and then filled the fresh water tank and unhooked elctric and water just to make sure the pump and everything else worked. Also I would suggest driveway camp a night or two just to make sure.
For other campgrounds.... mirror lake, rockport, and jordanelle are great places, they have hook up and primitive sites. I stay away from RV parks too, I just boondock mirror lake highway, MOAB and St George all the time.
