Good find there, my mindless friend! The goalpost bar on your hitch will help a lot.
I would approach this the same way I would hauling a large Hobie kayak or long surfski, which we do here all the time.
Remove any wires and mast BOBs (or position BOBs in the rear). Tie ratcheting stabilizer lines to the front and rear. Flag both ends. Avoid busy streets, turns and stoplights. Leave extra car lengths for braking.
The biggest safety concern, aside from clipping something with the 8' overhangs, is the panic stop/rear-ending and spearing someone in another vehicle. In which case, you'll wish you had BOBs on both ends. (Hmmm,..)
But there's the risk of denting or deforming the mast too, if things are too tight or too loose. Got rackpads?
6 hours is a long trip to drive without letting your guard down. Scout for suitable rest stops on the up way there. Order an extra-large coffee at the drive thru.
