New Ram and chucking in the 5ver

[carpetguy2]

My Father recently purchased a 2017 Ram cc. Lb. 2500 6.4 Hein
And a new 5ver denali 316 .
This new puck system people say they have no chucking but I drove it and it chucks quite a bit.
Any info on what he can do .
Thanks

Chucking is caused by the trailer, not the hitch. Various factors such as length, suspension design, and weight distribution will either minimize or maximize chucking. Don't give credit to a hitch mounted via a puck system if it is hooked up to a trailer with a tendency not to chuck. If your trailer has a tendency to chuck any solid joint hitch wether it be B&W, Andersen, Curt or Reese no matter how it is mounted will transfer the chucking energy directly to your truck.
Your choices to mitigate chucking are two fold. One, you can reduce chucking generated by the trailer via trailer suspension shocks or weight redistribution. Changing the length is not practical. Two, you can dissipate chucking energy at the hitch via air ride hitches or pin boxes or other devices such as MORryde and Demco pin boxes. All these methods will help keep chucking energy from your seat back. Some are better than others.

Don't get caught up with truck modifications such as shocks or air bags. Chucking forces are caused by the trailer and will be transmitted to your seat before they even reach the truck suspension pathway.

Durb, this is a great description of the cause of chucking. Most of the 'remedies' out there just don't seem to make a much difference. I know, I tried many of them short of modifying the trailer suspension. The shock absorbing pinboxes do not cure the chucking, it simply dampens it enough to make it acceptable. This is a common problem with FWs. Just look at how many aftermarket companies are making shock absorbing pinboxes and how many are sold. It's a good solution to a design problem that the manufacturers won't address. Jayco (and others) even offer the MORryde box as a factory option.

I wouldn't own another 5th wheel without a MORryde or similar shocking absorbing pinbox.

Another good one is the Roto-flex pinbox, I have it and it eliminated 99% of the chucking I had though it wasn't really bad to begin with.

Try adding some pin weight along with leveling. I use a air ride pin box which helps a lot.

[carpetguy2]

Not sure of his pin weight to be honest and couldn't even guess.know his trailer is 10600 empty.And master bedroom is in front with very little in front of the rv.
Just trying to help him figure it out.
I can lower the pin box only 1 hole.
I might try that and see.
Was seeing if anyone else had a issue like this
Thanks again

Pin weight too low?

[Old-Biscuit]

Pin weight..

What is it??????


Light pin (less then 20% of actual trailer weight) will cause 'chucking'
Add in nose-high.....chuck.chuck.chuck

[carpetguy2]

He is a bit nose high.He is using the B&W hitch puck .
I have a chevy 3500 with a hi rise hitch and a little nose high but his seem to chuck a little more.

What hitch is he using?

[MFL]

First thing, is he towing level? Some hitches and pin box types work better than others. I often find speeding up, or slowing down, depending on road conditions, can make quite a difference.
