Hadn't given this a second thought. Don't all pickups have part-time transfer cases with dog gears, synchros, and shift levers that engage the front axle locked to the rear and optionally engage a planetary gearset for additional gear reduction? Apparently not! Researching this has been...

Dealers have it because they can order. Usually, a PDF makes its way online. Is one available? I also could use Wagoneer, Grand Wagoneer, Grand Cherokee, and Grand Cherokee L order guides.

Needless to say, the Ram 1500 won. They got the best mileage with the Ram, but it could have been the worst and the Ram would have still won. No matter what little feature is better somewhere else, the Ram with its coil-spring rear suspension or air suspension, luxury car interior, and many...

From the 2021 Tahoe/Suburban press release from today: It will be interesting to see if they are willing to say what was an 8300 lb trailer rating is really 5000 lb or less if payload limits are adhered to. Or will they change the 10% rule or adjust the GVWR closer to the sum of the front/rear...

Again...from Australia. He covers lots of issues on hooking up, towing, using trees, and using winches. I thought it was interesting. For reference, Matt's Towing uses recovery ropes from these folks: https://yankum.com/kinetic-recovery-ropes/jeeps-suvs-pickups/

I ran into this video which seems to indicate it has as much of an advantage off-road as it has on the racetrack.

I believe this one has 40x15.50-20 tires

This is a sample video:

This is a link to Kelderman, which builds 4-corner air suspensions for trucks that don't have them. That includes adding a 4-link rear suspension like the Ram 1500s. It can cost $10+k to modify an F-250. It is a $1500 OE option on the Ram 1500 and only on the Ram 1500. https://kelderman.com/

One gives an interesting historical perspective. The other talks more about 3/4-ton vs 1-ton, which is really just a rating difference to be under Class 2b 10k lb limit for classification. The biggest exception to that rule is the Ram 2500's 4-link rear suspension...

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...

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...

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...

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...

This is a tow ball with a builtin scale: https://www.weigh-safe.com/product/universal-tow-ball/

I'm not a trusting soul. I found what I believed to be computational errors in all the online towing calculators i found. Errors that could be proven by just looking at actual CAT scale weights. So I did my own calculations...something a sophomore in mechanical engineering should have no problem...
