I have the Curt TruTrack 4P wdh on a 2022 Nissan Frontier with leaf helper springs added, towing the AIM 15bh. When I towed it away from the dealership when I bought it, I was using a Pathfinder with no WDH and it swayed like mad, and squatted way too much. I got a Curt WDH right away which helped alot but I still felt like the Pathfinder, with coil springs and very low hitch, wasn't comfortable towing this trailer, so I got the truck. Same towing capacity, but much more stable.
The Curt 4p makes it feel really solid once I got it adjusted properly, which took a few tries and wheel well measurements. It needed quite a bit of weight distribution to the front wheels. The 4P includes weight distribution and 4x sway control, which really helps how it handles. And I like how the Curt works vs the chain type hitch or the type where you have to insert washers. I feel like this is top of the line for a WDH. Now I see they have a new type where the head stays on the trailer instead of on the tow vehicle and you back straight into it to make it easier to hitch up. The bars stay in place on the trailer. Looks interesting.
