Try Sun Lake RV Resort at Exit 240 just South of fairgrounds on I-75 at Ruskin, FL. Great little campground. Very reasonable rates. Simple. Very Clean. Great location. Nothing fancy or exciting, just a "sweet" little hideaway....OH, also easy entry/exit maneuvering , open, big spaces, & great for big rigs if neccessary.
OR,...try Tampa East RV Campground off I-4 just East of Supershow fairground location (Exit 14 I think).
