Wanted to offer my experience with the Pro-Pride 3P.
My truck: 2016 F-150 with a 3.5 L Eco Boost, 3.55 rear end, max towing package and a 145 inch wheel base. It has a curb weight of 4890 lb, towing capacity of 11,600 lb and a GCWR of 16,900. Truck is stock other than Air Lift ride control air bags.
My trailer: 2017 Jayco 338 RETS. Dry weight 9130 lb. GVWR 11250. 40 ft from tongue to bumper. 12 ft high.
When I bought the trailer I knew I would be pushing my truck to the maximum capabilities. I wasn't concerned about the weigh as one search of You Tube will show videos of similar trucks pulling 14k loads up steep grades without difficulty. My concern of trailer sway. With the trailer outweighing the truck better than 2:1 when fully loaded, the large surface area inherent in a TT and my short wheel base I knew sway could be a huge issue.
Your concern should be payload. You are unlikely to be within the F-150 max payload capacity when loaded for the road with a TT that large. Just because you can pull it and eliminate sway means nothing when you are looking at a tongue weight of over 1000 pounds (probably well over). Even if your hitch receiver is rated for that much weight (most ½ tons are not), it leaves you with little room for passengers or cargo in the bed. I read threads all the time about people with much smaller trailers than yours who are pushing the limits of their payload capacity. I think you may be pushing your luck on this one.
