Trailer Weight Distribution

[319Quahog]

Loaded tires and pic 1 looks like the perfect weight distribution for the trailer.
Pic 3 is too far forward.
Pic 2 is workable, but be careful on turns and backing up.

Huh? That's a new one to me. Please explain.

Phrased this way, a light tongue weight will induce sway.

whats a new one? that the trailer nose should be slightly down? thats been a known thing for as long as i have been towing, you always want to be tongue heavy vs tail heavy.

want to test it, put your tractor to the front of the trailer, take a ride, put your tractor to back of the trailer, take a ride. when it starts swaying at 45+ you will get it.

Whether the trailer is nose down or up has little or nothing to do with how much tongue weight it has. And it shouldn't matter one bit unless the trailer has torsion axles, in which case you really don't want its nose to be lower.

And yes, given the option I'd much rather have too much than not enough tongue weight. That's a given.

But that the trailer's front should be lower and not level, or higher, is indeed news too me. The height of the trailer's coupler is dictated by the height of the receiver, and the shape (rise or drop) of the ballmount.

Once a load is added to the trailer other things come into play, including but not limited to, the tongue weight, the spring rate of the tow vehicle, the distance from the trailer ball to the rear axle of the tow vehicle, the wheelbase of the tow vehicle, the weight of the tow vehicle in relation to the towed load, and other basic physics things.

To sum it up, I still have no idea why the trailer should be nose down.

watch the video's above, they answer it. nose down tends to guarantee a higher tongue weight and stable tow.

Sorry, but I'm not into You Tube.

I'd like to see a torsion axle trailer have higher tongue weight with the front being lower. It would defy physics.

Either way, my trailers (with two exceptions) are either leaf sprung with balance beams or have air suspension. With the latter two it makes no difference (within reason) how level the trailer is or whether it's leaning forwards or towards the rear.

I could easily adjust the couplers on my trailers to make the fronts lower than level, but that wouldn't change the tongue weight at all, except on the two with torsion axles.

Alright, so you expect You Tube to explain what you can't?

Again, You Tube isn't my thing, but logic, physics, and experience does count in my case.

why should i waste my time, when the video will explain it 1000x better than anything I am going to type.

at the end of the day a light tongue is dangerous it induces sway, I've personally seen it when a load has shifted. i believe the towing books say 10% or more of the total weight.

tongue down pretty much forces a heaver tongue without scales etc. Again this was taught to everyone i know may even be in some towing books, its common knowledge here.

You can do what you want.

I don't think anyone would argue that too little tongue weight is a bad thing, and what I'm questioning is what the level (or lack thereof) of the trailer has to do with it.

Having towed with probably a hundred or so different vehicles, from flat towing to commercial 5th wheels, and at least with 40 different trailers, and over a few hundreds of thousand of miles, would you believe that I've learned something along the way - without consulting You Tube?

Again, tongue down is not a good indication of tongue weight. Only that the ballmount and/or coupler wasn't set at the correct height. Please allow a bit of common sense to apply here.

One other factor not mentioned is how much up force on the tongue while loading the tractor. Plenty of videos out there where there is enough up force to allow a truck to start rolling down the hill as an item is loaded.
