David , what kind of towing are you going to do ? One or two miles to the ramp or 100 plus mile trips . 1 or 2 miles to the ramp , pull it .
Long trips , well , for me you don't have enough truck.
The only way to know for sure what your pulling is to weigh it wet [ boat, motor, trailer ready to drop in and go fishing ] If you rig weighs 9k , Good luck.
Can you find a rig like you want to buy and try pulling and STOPPING it.
Lester
I'm not bashing you , just giving you things to think about.
