Chucking?

Well, I currently run Air Bags & Torklifts lower stable loads, I also have the uppers but have not installed them yet.
With my Truck camper.

Being unexpected illness in the family put the brakes to our camping trips.
But things seem better & we've gone once after the treatments that just ended within a week of that & we got back into it, But now looking into a 5th wheel.

As I research more & more I keep learning & the latest thing is chucking?
What the cheapest way to prevent it?

We experienced sever chucking with our rig. I started by replacing the factory kingpin with an 5th Airborne kingpin. That helped but we still had some chucking going on. I then installed Air Bags in the truck with on board compressor so I can adjust the pressure on the fly. This all but eliminated the chucking. In retrospect, I wish I would have started with the air bags, then, if still required, replaced the kingpin. Good luck whichever route you take!

Most chucking, if not all, can be prevented by moving the center of hitch forward of the axle. With short bed trucks, the tendency is to mount the fifthwheel directly on or behind the center axle. I have never experienced chucking in my own trucks. I have installed all my hitches 1"-2" forward of rear axle. I will never own a truck to pull a fifthwheel with a short bed.

I have a long bed.

Where is you hitch located in relation to the center of axle?

My Dad's RBW was used so much the sliding bar actually broke.

I bought the same hitch when I started RVing. I really did not like the CLUNK when stopping and taking off. A friend talked me into a B&W a few years later, I thank him often!

Current 5vr .no chucking

Previous 5vr.....slight chucking
Until I leveled 5vr and added shocks to it


Friends 5vr...constant chucking....until he finally let loose of some cash for a new hitch.
Old Old RBS sliding bar hitch I think his grandpa and Dad had both used
Bar had a semi-circle worn in it

I helped install the trailair pin on a fifth so going home the owner complained of chucking that was now a new thing. After thinking what would caused it I wondered if because of the fifth going up and down because of road conditions the less weight on the pin would allow the fifth to go back and same going forward. During the phone call talking to him he said he noticed the bar going across the pin was needing an adjustment and had just worked on it. Problem was solved.

I have a question for you. In your opinion what is chucking. I have towed 5th wheels since '05 all over the northern part of this country and do not believe we have any chucking. Porpoising, as in up and down, yes, but no front to back in the pin connection. Thanks.

Chucking...

Trailer constantly pushing/pulling against truck....regardless of road surface

That annoying feeling your truck is constantly being 'bumped' into

(like your kid sitting in backset kicking the back of your drivers seat) :B

Except 'chucking' is in both directions (fore/aft)

Thank you sir. I must say that I have never experienced that with either of my 5th wheels. I run a Reese standard rail mounted 16K hitch. Have a good day.

And thats why I told the OP to not worry about it until he gets a 5th wheel. Some have it, some don;t.

Yeah, sorry. LCI still makes them for smallish 5ers. Not for mine.
