I drive back and forth from the FL Keys to NJ more times a year than I want so I'm intimately familiar with all the FL Turnpike fuel stops especially Snapper Creek which is the last fuel stop on the Turnpike.
Snapper Creek has a sort of tight fuel stop for trucks. When entering the truck area traveling southbound, you have to make a hard left to get to the fuel islands. Once at the fuel islands, you have to walk across pretty much the whole car fuel area to go to the store and have them turn the pump on for you and pre-pay your estimated amount of fuel. Then you walk back to begin fueling. ONLY diesel at these pumps.
If it's early in the morning or very late at night, I'll use the car lanes where you can pull to the outside-most island and fill up using your card right at the pump for diesel. As I've had my card compromised at this stop previously, I prefer filling up there. I can even get my 40 footer while towing if it's not crowded.
Like all FL turnpike fuel stops, getting back onto the TP is a near death experience as you're forced to jump into the fast lane with cars going 80-90 MPH as your RV chugs along at a snail's pace.
Snapper Creek does have the BEST overnight spot in a empty parking lot as soon as you pull off the southbound side before you get to the police HQ and the fuel plaza. I've stayed there many times with no issues.
