Sure. You can pull it with no problem, but you'll probably exceed the payload capacity of your F-150.
Add a Reese fifth-wheel above-bed custom install kit (not the hitch, just the bed rails). Add a Reese "The Goose" hitch plugged into those bed rails. Hitch is complete and rated for a lot more than 10k pounds trailer.
Here's the "custom" install kit. Bolts onto the frame of the pickup without drilling in the frame of the pickup. The less expensive "universal" install kit will work, but it's a bugger-dog-bear to install because you must drill holes in the frame of the pickup.
And here's "The Goose" hitch.
Or for a bit more money you can install a B&W Turnover Ball gooseneck hitch.
DIY install of the TurnOverBall hitch is more difficult than installing the bed rails of the Reese hitch, but it's doable for a good handyman.
Now about being overloaded. Your EcoBoost drivetrain has way more power and torque than required to pull a 10,000-pound trailer over hill and dale. (I've pulled a 20,000-pound gooseneck thru the Hill Country of central Texas with mine, with no problem other than being severely overloaded over the payload capacity of my F-150).
So you want to minimize the weight you haul in the pickup when towing that load. Unload all the tools, jacks, people, pets, coolers, anything that weighs more than a handkerchief. You'll probably still be overloaded, so don't try towing at night with your headlights aiming at the stars, blinding oncoming traffic. Keep the speed down to not more than 60 MPH. Be certain you have the rear tires aired up to the max PSI on the sidewall, in your case 80 PSI. And air the front tires up to 65 PSI. You have the best trailer brake controller available as part of your Max Tow package, so be sure it's adjusted and works as designed.
Normal hitch weight of a gooseneck trailer is 20% to 25% of wet and loaded gross trailer weight, or 2,000 to 2,500 pounds for a 10,000-pound trailer. But you can safely tow with a bit less hitch weight, down to around 15% of wet and loaded gross trailer weight, or 1,500 pounds for your trailer. DO NOT
try for less than 15% hitch weight, because that makes for an unstable rig. I would put the bull tires of the tractor directly over the trailer axles, with the tractor facing forward.
Then good luck on your trip.
