I don't know if the OP is still looking (would be nice to find out what he chose if he did).
Just a note: A buddy bought a new 2018 F-150 all decked out for towing. Tow package, integral brake controller, extra wide mirrors, larger fuel tank. In other words, pretty much anything you could add to make it better for towing.
Turns out, the hitch itself was pretty minimal, IMO. And it was only rated for 1,000# tongue weight. So just something to think about, since it's rated for 11,000#. (He later traded it in for an F-250 and the hitch was what you'd expect - tied back into frame etc. more obviously.)
The F-150 was great to drive. I'd just be a bit loath to get up near limits on it, especially if you have a lot of tongue weight. For example many travel trailers trailers have closer to 15% tongue weight, which on 11,000# would be 1,650# and well over limit. Of course on boats it's potentially easier to adjust that by shifting the boat or wheel carriage on the trailer as long as it all still adds up correctly for trailer dynamics.
PS: Crandola, out of curiosity, do you know the tongue weight on your Cutwater, when loaded for cruising/traveling?
