Welcome to the forum and to Florida where I only lost 40 years before wising up and moving. A Park Model is not the same as a travel trailer in many ways... no 12V, no holding tanks, and not intended to be pulled around the country. Most Fla counties will consider any trailer/mobile home permanent and subject to their impact fees if you tie it down. Unless you use 6" diameter and 6' long tie downs put in with a machine to turn them, you are wasting your time and money.
While it's good to try and be a good neighbor, are your neighbor's units tied down and if so with what type of tie downs? If they have a U shaped top with a 3/8" bolt through it then they might do something in a hurricane, otherwise they are a joke. Depending on how close you are to the coast, hurricane insurance could be very expensive but it's probably your best option. Even if you could move it before a hurricane, the traffic trying to head north will make it nearly impossible to get out of the way unless you head out 4-5 days before expected land fall.
Actually a MH is the best option as after winter it's time to get out of Fla and head to the mountains.
