Is there such a person or professional that specializes in 5th wheel hitch/towing? We have the correct sized truck for our 2024 Momentum 320G but continually have chucking/jerking issues when on the road. If there is such a person in the Pacific Northwest, we'd love to get in touch with them!!
Welcome to the forum. I hope you find someone locally that can meet and talk to you about your towing experience.
As someone already said - it is a bit of trial and error. And there are few short answers or quick fixes for most of us.
One common issues to address could be that you want to be sure you load up the front to get some good pin weight. And as folks are already pointing out, some hitches are better than others.
You're going to get a lot of advice here. And before long everyone is going to want to know truck you have and what hitch. So you might want to up front about that.
I can give you experience with my current rig. It came with a Roto hitch (or something like that name) and the ride was absolutely horrendous. Chucking, jerking, porpoising, you name it.
I quickly switched to a MorRyde which was better, but still not perfect. With a MorRyde you have to match the spring rubber to your trailer's weight. At first (and even after asking MorRyde which rubber to use) I had the wrong rubber spring. Moving up to the next size up things were better. But I still wasn't happy as I felt there was too much back and forth movement starting and stopping.
I moved on to a long bed truck and a Reese Goosebox hitch (LB to loose the weight of a slider hitch and gain weight carrying capacity and the gooseneck so I could make adjustments. About the same time I got a MorRyde independent suspension on the RV. The suspension was mostly to make up for a lot of shortcomings in the Lippert/GD frame which had started cracking in the webbing near the spring hangars.
I have air bags on my truck too (have had then on the last 3 trucks). So between a rock solid hitch with the goose ball (no play, no slope in the hitch), being able to adjust the hitch air bag, being able to adjust the truck's air bags, and a nice RV suspension, I am loving my ride.
All-in-all this took me a few years. But 90% of the change was in moving on from the first cheap hitch GD provides (that Roto-whatever brand).
Hang in there. I suspect it'll get bette with some experience.
