Clunking on stops and starts

[Ram189]

I am brand new to the 5th wheel world. TTed for 20 years.

I took my new ride out for the 2nd voyage to try and judge distance, ect before taking a big trip at the end of the month.

When stopping and starting I get a noticeable clunk like the kingpin is riding back and forth in the hitch.

Is this normal or do I have a problem with compatablity between hitch and trailer. Hitch is too big or something??

I would not call the clunk any worse or better than I had with my travel trailer but that was 14 years old and the ball was getting worn so I contributed it to wear and tear.

All my stuff now is brand spanking new so I am minorly concerned unless you guys tell me it is normal.

Thanks
