You live in NJ. The rig you want is at a dealer in FL. Even if you do this deal, the FL dealer will charge you shipping costs from the factory to his dealership lot..
Because, more than likely, the unit was manufactured in the mid west...so you are going to pay the freight from the mid-west to FL.
...thus, no freight savings to you.
I'd deal locally or as close to you as possible - cross country is not the best way to go.
The only way I'd do a deal that long distance would be if the out the door price savings was significant.
