I stayed at Silver Dollar RV last winter for a long weekend. It is a 55+ community. It is in a rural setting, but close enough to shopping and restaurants. It is right on a golf course. I liked it and my wife liked it. The monthly rate with all utilities included is $695 (prime season), except cable tv is extra. The transient RV area is pretty small, maybe 40 to 50 spaces set under large oaks and pines. It is 30 minutes northwest of Tampa, 20 minutes northeast of Clearwater, 20 minutes southeast of Tarpon Springs.
edit: There is a shooting range about a half mile away that you can hear occasionally.
