Pintle hook trailers are almost always "wagon" style trailers with very little hitch weight. The front axle on the wagon pivots during turns. Look at the rear trailers on double and tripple longhaul rigs and you'll see a big difference in the way they're made compared to the fifth-wheel first trailer.

Also the space between the pintle hook on the tow vehicle and the lunette ring on the trailer of those "pro" trailers is tiny - so almost no play in the hitch. The pintal hook and the lunette ring must be made for each other so there's almost no play between the hook and the ring. So if you have more than one lunette hitch trailer, they all must have a lunette ring that perfectly matches the hook on the tow vehicle.

I grew up as a farm boy, dragging wagon-style cotton trailers and grain trailers. Not fun. Very low safe speed limits. Fine for pulling across a sandy or muddy field at low speeds, or a couple of miles to the gin or grain elevator at maybe 45 MPH on paved roads, but I'd hate to have to drag one hundeds of miles.

If you want a trailer for hauling heavy weights on the highway, then stick with the proven gooseneck or fifth-wheel hitch. The pintle hook hitch is a "bumper-pull" hitch, which is never as good as a hitch mounted over the rear axle unless you can include a Hensley Arrow hitch in the setup. And you can't add any sort of weight-distributing hitch, Hensley Arrow or any other kind, to a wagon-style trailer.

Also note that the receiver on your truck is limited to maybe 12,000 or 15,000 pounds max trailer weight. So if you want to tow a heavier trailer than your receiver is rated for, you'll need a much-beefier receiver rated for the max weight of your trailer.
