I don’t believe you need a WD set up, but it could have its advantages. Short drives you’d never
1. WD setups reduce hitch jounce/bounce on lousy roads, on a long trip this can take a toll on your leafs and your back.
2. it will help shift the rear weight to the front, depending on how heavy the tongue is, this may make your truck ride rougher. For this reason (and laziness) I personally don’t use my bars for an hour or less drive.
3. If you’re still on the duratracs, they’re squirrelly. My v nose made my 21 sway and squirm like crazy, in ways my 17 never did. With that being said, the additional pressure of the WD will reduce that pivot point, giving you stability at highway speed.
Typically I’m towing my camper, which has a tongue weight of around 900lbs. On my 17 f350 with the camper package, I would go back and forth with using the WD.. until the last trip where I decided to leave it at home. Over 2 weeks and roughly 4,000 miles, I noticed the truck sitting lower and lower, before it never touched the overloads, by the end they were fully engaged. That trip was the worst for driving, I had to keep adjusting the hitch to compensate for the squat, all it did was bounce (my back had it), and sway on the freeway when passing trucks got worse and worse, where normally I’m towing 80-85, I was reduced to 70. I’d buy the set up and try it, the Anderson kit looks great, I have a basic Reese with 700 bars, it works, it was cheap, and when I drag it across rocks I don’t feel bad.
