Hi,
Some input on weight:
Boat: 8221#
Motors (assuming F250 or F225): 1200#
Fuel: 306g at 6lbs 1836#
Water and head: 45gal (inc water heater) and 10gal, 300#
Gear est #400
So you are just about 12000# to be safe. The trailer looks to be sufficient.
The beam is listed at 10'7" so you will require a special permit and as previously stated, this is a no brainer due to insurance and legal potential issues.
I have seen them towed around in yards not on the road. It is a big boat out of the water, not a typical trailerable boat. It can be done if you have the right rig and trailer. Not something I'd like to do with mine, but to each his own.
Good luck!
