E.G. Simmons Regional Park at 2401 19th Ave NW, Ruskin, Florida.

Nice location and ideal if you like fishing. Other than that, there's not really much going on here. You make your own entertainment...the beach area doesn't really stand out as a place you'd want to swim at; the kiddies play area is somewhat spartan and the toilets (restrooms) I briefly visited were dire. You bring your own food and drink and find some shade perhaps to read a book.

If you're travelling through this part of Hillsborough County and looking for somewhere to park up your camper van then yes I can see this place as a reasonable choice in the area. The entry fee is low and the overall environment quite pleasant - just make sure you have your own private bathroom on board!
