South FL is trucker hell for so many reasons. I found a decent place called "discount truck parking" around Powerline and Copans, but it was still over $25 a day. There is a tiny truck stop off the tpk in Coconut Creek, its always packed, but there is some street parking in the vicinity. If you have a reefer there is the produce/farmers market in Pompano. There are a couple places in Opa-Locka on 441, but make sure you are empty or you will get unloaded involuntarily. But in general South FL is just disgusting and awful for truckers. The Turnpike has rest areas, but any more than 10hrs they will definitely tow you. Fort Pierce is where you can legit park, then deliver, then GTFO empty/deadhead all the way to Georgia like everyone else does seems to be the most common way.
