Well, I guess there are 2 sides to this show...
I know some believe heavily on WD in all situations and some don't.
Our one ton trucks are rated to carry stuff, not to get the occasional bag of groceries. You can do that in Smart Car.
The bed of the truck is designed to carry a payload, whatever number that happens to be. And it sure as heck is a lot more payload than the tongue weight of a TT, Cargo, TH, whatever. You are putting the tongue weight on the back of the truck, not the entire weight of the load behind you. I have had close to 3 tons in the back of my dually.
Sure it squats a bit but I find that a little weight on the back really helps the ride and handling, even on my dually that is already loaded by 2000 pounds of rack and tool boxes.
I have never used a WD in all the years of towing and all the different trailers I've towed.
I just sold my 25.5' TT in favor of a 27' TT. It came with a WD hitch and bars etc. First trip was a rush after I bought the rig so I just hooked up and left for a fishing trip, with the thought I would look at the WD later. After all, I have never used one yet.
Although I knew I had more weight back there, the tow was perfect. No sway, no handling issues, no problems when a semi truck would blast by the other way, no issues in a sidewind, nothing.
I really can see the need for WD if you are towing with a half ton, but on a vehicle designed to take a load to town, I see no purpose in a WD setup. The front end will not become light - it just won't happen. There is not enough weight on the the back to make any significant impact on "lifting the front off the ground"
I am careful when I tow - I don't drive 80 miles an hour, although I think I could. Some common sense prevails. But I do tow at 65 to 70, road and traffic conditions permitting. I have been in emergency situations, such as jack-knifing on black ice a couple years ago. Quick attention to getting it back straight again had my TT fishtail a bit, but I never lost control. The towing ability of a 1 ton dually really shines in these situations.
Yes, WD has its place, and in my opinion it is geared more for TV's with less capacity than the 1 tons. Smaller, lighter duty vehicles like Suburbans, Expeditions and such trucks that are built more for comfort than being a workhorse.
