Here's a mind boggler. A WDH will induce directional instability . Remember we are talking about true sway, not the tail wagging. This is a twisting motion. Say the when trailer lurches to the right, then the WDH is going to transfer that motion to the right corner of the TV, suddenly your TV is now pointing to the left. From experience,all blood in your hands gets squeezed out as you tighten your grip on the steering wheel.
I use a Equilizer hitch. Because I run on gravel, I didn't want a heavy spring between the truck and trailer. On gravel, ideally you want soft springs and lots of travel in your springs. So when I got the hitch, I got a 400# bars. The sales brochure said 410#, a bit of a lie, and the tag said 460# dry. I'm sure hitch weight is more.
Tires will affect your steering experience. My brother and his wife loved the Jeep Cherokees, they leased them so they had a few. After the first one which had Michelins , the next one had Goodyears. My sister-in -laws asked what was wrong with this new one?
I chuckle at these young guys and all their steering add-ons on their big Rams and their squishy mud tires.
