You ever see "Movin'" ?
...I would tow my stuff, but that's me. I like to know where my stuff is at all times
If add the cost to ship the Harley, that's $2900 for someone to move your stuff. Fuel from Cali to Florida is a fraction of that. And if the movers don't get your stuff there on time, you'll be sitting around anyway...the time lost going slower might not mean much.
Good luck with the move Paul. And drive safely (w/ or w/o the trailer).
