Learning GVWR and chucking the hard way.

[phonemannn]

In my experience, same 5er, GM chucked by far the most. Ford good and Ram best. All HD duellies. All 2015 or newer...GMC Denali was terrible. Really...

If the truck is contributing to the chucking, what would be the thing to look at? Springs? Shocks? Tires? PSI in tires?

You statement is of obvious interest to me given my truck

I also have chucking issue. I tried to move all weights to the front of the RV , so far nothing helping.
I also need help to eliminate the chucking if possible.

I have
2019 Ford F250, Payload 2248
2019 Reflection 150 Series 295RL (GVWR 10195, Hitch weight 1391)
B&W Companion Hitch, RVK3300
LoadLifter 5000Ultimate Plus - 89399

How much air are you running in the airbags?

How much air are you running in the airbags?

About 20 - 25 psi, the truck is too high.

I have bags on my 3500 from my previous 5th wheel, but run them almost empty for the 260RD.

Rides great.

What about installing air bags and a MorRyde hitch? We used this set up with our Reflection and it solved 90% of the herky jerky action. We now have a Trailair kingpin with a B&W hitch and air bags and it works great... (I should've mentioned with a Solitude we bought a year ago..)

Is it chucking (a back-and-forth motion), or porpoising (bobbing up and down)? They are so close in ride comfort sometimes it’s hard to tell. This has probably been revised and discussed thousands of times on RV forums, but still need mentioning again I think for this discussion.

If chucking then maybe it’s a different pin box that is needed. I put on a MorRyde pin box on my rig (see my signature) and it helped - a lot. The Roto-Flex just pulled and pushed and made bad noises when starting and stopping.

To try to fix a bit of the chucking and a lot of the bouncing/porpoising I put AirLift air bags on my 1 ton. I really can’t tell if it helped or not. I’ve run with 5 lbs and 70 lbs. I think 60 to 70 lbs is better; it gets weight off my helper springs.

Anyhow.... if the 1500 rode better then I’m going to guess air bags will help more than a pin box.

It’s really too bad we have to spend more money after our large purchases to make things better.....

The OP has a 150 Series Reflection.

The pinboxes are not replaceable.

An FYI, the haulers that bring these in to us everyday always say that the GD products tow the best of any they haul.

Just need to find the right combo of truck/trailer.

I have what might be a stupid question....if the trailer rides close to level and i want to increase pin weight to help solve chucking, is putting weight into the bed of the truck going to have the same effect as putting the weight on the trailer?
