Chuck chuck chucking

Have a 18K B&W Patriot hitch and a Trail Aire pinbox. I get more chucking than I like. Trailer is loaded heavy in the front all the normal things to help get rid of chucking. My question is..I have hitch setup so the pin is as far back as the adjustment will allow. This puts the pin about centered over the axle. I can move it ahead 4-5 inches. Will this help to eliminate chucking? Towing with a dually, everything sits nice and level.

I don't think so.
We have several top rated lightweight RV type hitches.....your B&W is one of them.
Chucking can show up with any GN/5th wheel hitch on any combo even my tandem and triaxle GN trailers. Having five one ton drw trucks (chevy/Ford with different wheelbases/year models) on the road pulling my different trailers we quickly found which truck trailer combo had no issues and which combo was a real pain in the azz to operate.
I've had some trailers that chucked hard when the deck was loaded heavy.....and others didn't.

There is no one thing we can do that works for all truck/trailer combo's that eliminates all chucking issues.

The B&W is the best there is. Also comes from a fine company. Look them up on the internet and learn about how they are made. Any problems I am having with chucking are not because of the quality of the hitch.

Bad overpass sucks for us but the alpenlite just takes it very easy with a big lift and it is over. we are well matched. Old stuff that is working great for us.

You have a good setup along with a heavy RV that has a good pin weight!

Now there are times hitting a big dip or bad overpass that will give you one HE!! of a jerk but that is not possible to correct.

We had the same issue with chucking on a trip to Kennedy Space Center. I shifted the hitch forward, increased pin weight and lowered the trailer tire pressure. Took a second trip to Titusville (KSC) about 6 months later, same route, good old I95, quite a difference. I'm going to try and increase the pin weight more, it's at 20% now, maybe a bit will help. Good luck with your rig. The closest CAT scales is only 4 miles away from us so that helps.

Why do say "It was scary at times"


When you have metal clanking LOUDLY behind you it makes you wonder if something is braking.

There is no getting rid of of the chucking. RR tracks, road joints, bridge transitions, all have an unpleasant effect to one degree or another as each axle of the truck & trailer pass over them.

Too bad road surface joints & bridge transitions are not at 45 deg angles.

I've had chucking since day one. Installed a Morryde and that help some. Pin is 20% and won't be any heavier. Towed with two different trucks. I currently use a B&W and have used an Andersen rail mount. Absolutely no difference in the with between the hitches or trucks in any combination.

I only get chucking on certain types of rougher roads. I get a slight push pull on bridges. 90% of the time it's fine.

Had a TT before and the towing was horrible. Two trucks, several different WDH's and the jerking never left.

I figure there's gotta be some kind of give and take. Even my 5x10 utlity trailer loaded with 4000 lbs of gravel tugs on the truck.

There's no one size fits all remedy. Everyone's towing with a different trailer with a different truck.

It's always the same old dance. Get Bilstiens, get air bags, your hitch is noisy, adjust your brake controller, ignore it (that's a new one). Fact is, all fifth wheels have different towing dynamics and some chuck worse than others. Mine didn't chuck over glass smooth roads but in my area those are very few. Having your wife hold her chest while in the passenger seat translates to more than hitch noise. This was my condition with zero hitch noise. Ignoring it wasn't an option. The trailer when it hits a bump rotates due to the dual axles and causes the pin to push down and forward at the same time. Your air pin box is allowing your pin to push down but is doing nothing for the forward motion, chucking.

Shocks will not address the chucking problem. Think about it, your truck is being pushed back and forth by the trailer. Why would a vertical suspension component that is disconnected from the energy path of trailer to truck make any difference? They would make a difference regarding the forces when the truck goes over a bump reaching the cab. Might be the reason why many feel they help with chucking.

Air bags could help with chucking if they were aired to the max plus your pin box bag. This would make a stiff joint to the ground and would reduce the trailers tendency to rotate. If the pin doesn't push down then it isn't pushing forward. This is an impractical scenario as the energy the trailer and truck generates when going over bumps needs to be dissipated elsewhere such as frame flex and tire deflection.

There are solutions, gonna be expensive.
