At the risk of whipping a dead horse, my comment is, unhitched tongue weight means little when properly distributer by a WD hitch.

People ask where does the weight go? The weight does not go anywhere, it is redistributed to the truck and trailer frame. How do we know this? There was a decades old advertisement showing an Oldsmobile Torenado with front wheel drive pulling a trailer with the rear wheels remove.

All the tongue weight was transferred by the WD hitch to the car's front axel and the trailers axels. There was no weight on the rear axel so the wheels were removed.

You would get the same effect if you welded a large I beam to the trailer frame and the truck frame. The tongue weight is still there, but it is spread out along the length of the I beam. You would not even need the hitch ball. Of course you could not turn either.

As mentioned, either you believe the numbers or you do not. If your WD hitch is adjust so the rig sits level and the scale shows your max axel weights, max cargo, (usually a bit less then the combined front and rear axel weights} and your trailer axel weights are okay; with about 10 to 15% of the trailer weight is on the ball, then your tongue weight had been properly distributed.

But what if you put some super gonzo, heavy weight trailer and WD hitch on your poor little half ton? When you level the rig and go to the scale, it will show that the redistributed weight exceed the weight limits of your axel or max cargo rating or both.

There is no free lunch, if your trailer is too heavy, it is too heavy. Folks who are close to there max cargo will sometimes shift the load inside the trailer. This of course has its limits also.

So again the tongue weight of the sitting trailer means little. It is how it is redistributed to the axles by the WD hitch that is important.

To heck with all the drivel about tongue weights....
I wanna know why HP would randomly want to search your vehicle if you are at a weigh station and if you mean people in general or just you in particular. And why your be concerned about that?
Remember, you bring it up....lol.

You can lead a horse to water, but you cannot make it drink.

That sticker on your receiver hitch tells you what it is rated for.
That has nothing to do with the axle load weights. You state that yours is 1130#.... But you really do not know what your TW is, as you only measure it with WD engaged. You cannot determine TW that way.

This means that it is very likely you are OVER the hitch rating.

You will only know, IF you weigh it properly.

Now it is your decision. You have now been lead to the water.
Drink the water and know the truth.... Or don't and not know.

Your money, your choice

The debated comes down to the tongue weight your hitch carries.

Without the WD the full weight of the hitch is on the ball and the rear springs compress.

With the WD hitch some of the weight is transferred from the ball reducing the rear spring compression and reducing the axel weight and increasing the front axel and trailer axle weights.

Either a person believes it or does not. It may make for an interesting discussion but it has little impact on the overall RV community.

Huntingdog makes a very valid point about tongue weight and the rating of the hitch. Just because all the axle weights are in spec doesn’t mean the hitch is not being overloaded.
Your hitch has a rating for no WD and one for with a WD.
For example, if your hitch has 1000 pound WD rating and your tongue weight is 1200 pounds, you are overloaded, regardless of what the WD does.
It’s fairly easy to determine tongue weight. I use the 4’ beam and house scale system. Then I’ll go to the Cat Scale to get the axle weights.

A WD hitch does not remove load from the hitch ball. It transfers load from the rear axle to the front axle, but that load is NOT the tongue load. Tongue weight is still right there, on the hitch ball. Ad I said above tongue weight could be zero, and the WD hitch would still move load to the front axle and the TT axles.


Read the sticky. It explains it all.

I doubt we can reach him, as he doesn't want to know the truth.... But at least we are letting others know that he is wrong, and where they can find the info that explains why.

That sticky has some very sharp engineers discussing WD.
