If you're pushing ANY component THAT close to its limits, you're asking for trouble. And that includes (ESPECIALLY) the loose nut behind the wheel. If you've never towed a trailer as heavy as this one, you DON'T want to learn with a truck that can barely handle it. Learn with a truck that can EASILY compensate for the mistakes you'll make. After you've put a few hundred thousand miles behind you & it, you can try your luck with a borderline (1/2-ton) truck.

That doesn't make sense. The receiver mfr.'s engineers can't know what kind of ball mount you're going to stick in there, or how far from the receiver the tongue will swivel.

Each one of those components have a weight carrying and/or weight distribution rating based on the j684 standard( this a requirement). Which ever is rated lower, the extension or the receiver hitch becomes the limiting component. All components that makeup the “Hitch” are rated for the Max GVWR of the trailer to be drawn and the Max vertical load on the ball. This includes the receiver, ball mounts including WDH mounts. How does the receiver manufacturer produce a weight carrying and WD rating without inserting each type to perform the test? I encourage you to read the j684 standard which describes in detail how testing is performed. If you can’t find it on the web I can supply it.

The extra long hitch extension ensures that your 5er doesn't hit the tailgate when you turn. Genius!

So Smokeywren when I weighed my truck on a cat scale with WDH not tensioned up and the difference of the Tow vehicle by itself was 760 lbs that would be my tongue weight. Now when I tension up my WDH I should gain at last 100 lbs for payload in tow vehicle.

Uh, no.

That tongue weight doesn't change. A weight distributing hitch just distributes that weight between the front and rear axles rather than all on the rear axle.

And that's on the back end of an F-350 DRW. Maybe he's got a bed cover. Maybe he just couldn't fit a 5th wheel hitch in the bed with the 6 ice chests of beer.

Tongue weight doesn't change, but the properly set up WDH does remove some weight from payload by leveraging it to the trailer. That is what he was asking. On my 16 the truck gained back 360 pounds when the hitch was engaged.

Not exactly. We're into semantic here, but you're on the right track.The WDH when properly adjusted will distribute about 20% of TW back to the trailer axles. So instead of 760 pounds of hitch weight using payload capacity of the tow vehicle, you would have (760 minus 20% = ) 608 pounds of hitch weight using payload capacity of the tow vehicle. So compared to not tensioning the WDH, you would have about 150 pounds of unused payload capacity after you adjusted the WDH.

The actual TW doesn't change, but the payload capacity used by hitch weight does change - because some of the hitch weight is distributed off the axles of the tow vehicle.
