I just called and the dumb girl answering couldn't tell me how many parking spaces are at their truck stop. She said they still have a few right now, I said no, I'll be there tomorrow. She said oh they'll have some available then also. I said no, how many total I'm trying to gauge whether to stop there for the night some other night. She said I'll be fine. I can't exactly trust her answer. I just needed to know if they have 50 spots total, or more or less. Just give me a freaking number! Dang.
OP, There are about 10 spots there and about 15 spots behind the BP gas station across(west-bound side) the street. There is a Sam's Club lot on the west-bound side trucks have parked in as well. I was there 3 weeks ago and live just north of there.
It's Ellenton, FL below Tampa. The funny part is they have showers but no parking. You can turn right and park down the street at a motel that charges $10 for parking and walk back if you want. The Cookeville, TN Pilot is similar. They use to have parking across the street but stopped it for the trash.
