Why did you change (upgrade) pin box?

We have a new 41' fifth wheel. We have a new to us Silverado 3500 Diesel DRW coming next week. I need to have a 5th wheel hitch installed so I'm looking for recommendations for that but I have seen many people posting about replacing their pin boxes, why? Is that something I should consider? Just a note, this is our first 5th wheel, we are full timing and we plan on traveling 8 to 10 thousand miles per year (I know we're jumping in with both feet).

We replaced our Trailair pin box (came with the trailer) to a Trailair Triglide pin box. We did this to help with chucking. It has helped a lot.

We already had a hitch, and I haven't seen anyone that has replaced a hitch to get rid of chucking. Oh they say they have this or that hitch and no chucking, but they don't know that their hitch has anything to do with it, because they don't have experience with the exact same setup with another hitch that had chucking.

I had no chucking with my 88 Jayco and 88 F150. It must have been my cheap hitch that only moved front to back, not 4 way movement like todays hitches.

However, if I was to start from scratch and money was no object (which it always is), I would look at an air hitch and a anti-chucking pin box. Then you eliminate the bouncing and chucking. Assuming you have it anyway. You really don't want to buy and hope you don't have any issues, then have to buy again.

Air hitch and solid pin works well on most units. We had a DRV that had a Trailair 5ther pin and a B&W Companion. It chucked with a 4400# pin weight.

I was just checking the boards and came across this thread, and thankful I did. We are considering a new 5th wheel in the next 12 months, moving up from a TT. I am going to have to learn a lot about hitches, etc. That said, the term "chucking" has been used extensively in this thread. Can someone explain what that means?

It's the push/pull feeling. It can be so bad that it feels like your guts are going to be ripped out of your body.

It generally happens over rough roads at higher speeds.

It differs from an up/down bounce.

It can also be so subtle that your neck and shoulders will be stiff and sore after a long haul,but you will wonder why.
After I got the heavier truck all that fatigue vanished.

TrailAir pin box with Triglide and B&W no checking with 4,500# pin. No chucking before the TriGlide.

Above with Bilstien shocks and air bags set at 30# loaded make a great ride. Near 29K combined load.

Great information everyone, thank you. The truck I bought already has a gooseneck hitch in the bed so here is what I was thinking I would use:

Mor/Ryde 5th Wheel Pin Box on a B&W Companion 5th Wheel Hitch. How does that sound?

Mine checked badly with that. Had 2005 Chevy dually and 4400# pin also

Regardless of spec. 4400 pin weight is too much to ask of any 1 ton or 3500 series. Brake size and pad or shoe area is the reason. Anything over 3k IMO needs more truck.

It is what we use. Replaced the Trail Air pin box. Wife complained about the chucking, replaced the pin box, complaints went away.

My current Teton we have 5280# pin weight. No problem what so ever.

Any of the three Dually's on the market can handle that weight. RAM has the SAE J2807 backing of what they claim. My combined is near 29K aND PIN IS JUST UNDER 5K. 2011 RAM Dually handles the load with ease in all conditions.
