They are not common, but they seem to exist: https://www.goldrv.co.uk/parts/20/hitches/1042/weight-distributing-hitch/

There seems to be an inconsistency in the measurements on the front. Was the hitch on the truck in the unloaded measurement? Assuming the 500lb estimate is correct and the hitch is 66" behind the rear axle, and this is a 144.5" wb truck, it is indicating a front-wheel rate of 460 lb/in and a...

5000# is a light trailer. You shouldn't have any problem with a WDH. Do you know your tongue weight? What were the front fender heights before hitching, after hitching, and after adjustment? The side-to-side movement sounds concerning. If looking underneath while someone else causes the sway...

I'd agree. The Premier LTX is a newer version of the Latitude HP that came standard on the QX56, a relatively high end SUV in its day. My own experience is they are silent, good handling, and good in rain. I don't have winter experience with them because we change tires. Their TW isn't the...

I've been pointed at some DOT studies from the late 1970s. I haven't been able to get a copy of this report yet, but the summary is interesting. One of the cases was using a 1970s station wagon to tow a 31ft RV. That Wagon would have specs between a Tahoe and Suburban: 228" length, 125"...

Do you use winter tires or the all-season tires year-round? Costco has $110 off on Michelin through 10/1. The Premier LTX is $664 installed. The X Tour A/S T + H $656 installed. I have the Premiers on my QX56, but use a winter tire from December to March.

The Curt hitch is interesting...a rather unique way to keep the trailer from turning.

This device mounts on the trailer monitors yaw rate and selectively applies the trailer brakes. I had found a similar (but less sophisticated) device sold in Australia, and someone pointed me to this. Activation of the trailer brakes is the easiest way to control sway. The 4-bar linkage hitches...

I think the North Edition on the Big Horn is the best value and the most attractive Ram 1500 from the factory. Just wish we could get the North Edition with 18" wheels on the Limited!

Interesting...Airstream in the UK has 3 models. They all have a 150kg hitch limit. The biggest has a Maximum Technical Permissible Laden Mass (MTPLM) of 2400kg and a Optional Upgraded MTPLM of 2680kg. They represent tongue weight percentages of 6.25% and 5.60%. Max.

The paper: An experimental investigation of car-trailer high-speed stability This is from the University of Bath. It is on point but didn't test with a WDH. They looked at tongue weight (they call it nose mass), trailer mass, moment of inertia, tire pressure and axle position. These are the...

What was the trailer axle weight? DId you way the truck without the trailer and with the WD disconnected? What is your door sticker payload? Do you have dimensions for the ball-to-axle dimensions on the trailer and the rear overhang?

These aren't mine. I was looking for something like them to answer a post on another forum. But they are an excellent description. In it, a 3025# trailer starts with 450# tongue weight. After the WD hitch installed, the load on the ball increases to 1039#, but the net weight on the tow vehicle...

These are actual CAT scale numbers posted on another forum: My WDH is the Blue OX Sway Pro. With 1k bars. I put it up to the 9th Chain link as called for in the book, and the Tech who installed the the Blue Ox First, my TV is a 2014 F150 XLT 4x4, Supercab, 8 ft box, with Max Tow Package, and...

That video is the one above. But it was about the location of the disturbance, not the tongue weight. Yes, it is hard to shift 10%...but not impossible. It is just a matter of moving stuff from the front to over the axle. It is only a little easier in a car trailer, since there are tie downs in...

I finally got an answer that was meaningful on the 10% tongue weight. I extrapolated on stability. Sway is a dynamic situation. Tongue weight (as normally defined) is a static measurement. Basic physics dictates that one is *not* the same as the other. The reason you see ~ 10% tongue weights...

Thanks...the key is that at max trailer weight it has a MAX 10% tongue weight.

An interesting note: while some sites recommend a 10%-15% tongue weight, the receiver mounted on the truck usually has a MAX tongue weight that is 10% of its MAX trailer weight. That is, it appears at maximum loads the receiver is designed for a MAXIMUM tongue eight of 10%. There are a few...

I'm mixed on the Air Lift 5000 on the Ram 1500, although all the stainless parts on their Ultimate version are nice. They require cutting the jounce mount while others don't. Potentially an issue if it is removed. Timber Grove, recommended by another poster, is one which doesn't...

Do you have the air suspension? Are planning to weight the setup at a CAT scale station?
