Could someone explain what chucking is? I have pulled a fifth wheel for thousands of miles and either I have had chucking and didn’t notice or I didn’t have it.

chucking is when the pin and coupler are not tight together. You notice it more on a semi.

Thanks, the video was good. Maybe I don’t feel it because I use an Andersen Ultimate hitch

Maybe you have a properly setup RV and TV with a good percentage of pin weight.

With your ANDERSEN properly placed and it properly torqued it shouldn’t attribute to chucking.

I have much reduced chucking after switching to EZ Flex suspension.

Chucking, not to be confused with upchucking.

Basically it is a forward-backward push-pull feeling going down a less than smooth roadway. I have little to none on most highways. But do have it on some, most often those are concrete rather than asphalt highways.

Certain concrete slab joints can cause chucking with any truck/trailer/hitch combo (not all). Some sections may be several miles long or maybe a few blocks long.
Years back it was referred to as freeway hop.
I've notice it with GN/bumper pull/5th wheel trailers also over the same sections. Some were just noticeable on the rougher roadway joints while other trailers were severe enough I had to slow down.

We had chucking with our old setup, but changed over to the Anderson about 2 years ago and have felt NOTHING! Not one single time with this hitch.
