Hitch Pin Help

Just bought a new 33IK Silverback and using a Curt Q25 hitch.

Trailer is 37' total length and a GVWR of 14K. Pulling with a 2017 GMC 1 ton SWB Diesel.

On the way home I noticed chucking. I'm thinking about either a Morryde or a Trail-Air hitch pin.

I'm looking for real world experience and not opinions.

Thanks for your input.

  • My cardinal came with the Mor/Ryde pin box. I don't get a lot of chucking, except for certain highways. Seems to absorb the shock, but you can still feel it in the truck. Never towed without it, so I cant comment on the improvement.
  • Thanks all for your input.

    5th Wheels are new to me as I'm used to a TT and know very well about tongue weight.

    Never thought pin weight would cause the chucking but makes sense now that you have brought it to my attention.

    So I will load the trailer and see what I get with that.

    Also, I do plan on putting on either Joy Rider shocks or another brand once the 1 year frame warranty is up. I did this on my TT and it did make a huge difference.

    As for level, it is pretty close and still giving me about 5 1/2 - 6 inches of clearance.

    I will report back in a couple of weeks when I have taken it on it's maiden voyage.

    If anyone has put on the morryde or Trail Air I would still like to hear from you just in case the above doesn't help.

    Thanks again for all you input.
  • X whatever on loading your trailer. IMHO most chucking is caused by too little pin weight for 5ers and the same can happen with bumper pulls. There's a sweet spot you've got to figure out (usually by trial and error) that will put enough weight on the front to stop it.
  • ALL above good advice.

    Add one thing ...get weighed 'camp ready' (stuff/people/pets more stuff etc)

    Chucking is alot about pin weight and trailer set up

    one of the root causes of chucking it too light of pin. so get a load in it. Find out where the FW tank is and if even slightly forward of the axles, fill it and see if that helps.
    Does the 5er sit level when towing nose high or low can also cause it. Then see if you have shocks on the 5er, they will help with the total towing experience.

    Agree with this line of thinking. Make adjustments to the hitch and/or pinbox height to get it level. Load it accordingly, try to make other adjustments first. We have a Mor-Ryde and it helps quite significantly, but that's certainly not the first thing I'd do to help minimize chucking.

  • I have a 2013 F350 dually pulling a 36' Bighorn with a GVW of 14k.

    Starting my 4th year of fulltiming and have had the MorRyde pinbox since day one. It works great and is SIMPLE. Seems to really knock down the chucking. The rubber donut that surrounds the metal pin absorbs the back and forth motion.

    I also have a Hensley air hitch which eliminates lots (most ?) of the up and down motion that can be transferred from trailer to truck or from truck to trailer. Between the two of them I have a very nice ride.

    I am a believer that it's smart to try and eliminate as much going-down-the-road wear and tear as is reasonably possible on both the trailer and the truck. My trailer came with 4 shocks which is a good start I think.
  • So much of what your experiencing is generated by the difference in wheel bases creating two or three different sets of harmonics. Good luck trying to get rid of it. BTW,if you need to add suppliments to your truck, you need more truck.
