As stated in an earlier post it is illegal to pull doubles in Florida, and dont believe those who tell you different and that you can get away with it. It is getting more and more attention and the leo's are getting less tolerant of those that attempt to do it.
As far as having a golf cart , I love having mine with me, gets me out alot more than I do if I don't have it, they are great conversation starters with some modifications, ie. lift kits etc.
Fortunately I have a toy hauler so I do not face the issue of taking it with me that those with regular trailers do. It was one of the reasons we went toy hauler,it was that important.
