I don't think you need to be concerned. If you are happy with the ride leave it alone.

As i have mentioned I have an air bag pin box and with my 6k pin I guarantee if I had the MORryde solid pin box I would have cracks.

What brand/model pin box do you have? I’ve been thinking of upgrading my MORryde pin box. Last time I weighed, I was close to 25k with 5.5k on the pin. So far no frame cracks yet but an air ride type pin box makes sense to me.

2020 from what I know has the cracked frame issue fixed.

My pin box is a TrailAir TriGlide air bag unit. They don't make the TriGlide portion any longer. The TrailAir is 21k rated.

I'm surprised that this is still circulating on this forum. The frames broke because the owners were doing a tug test to make sure the jaws were closed just like you would do on a semi truck and trailer. The reason this failure doesn't keep showing up is because these people were performing it as if they were driving a semi truck with all the weight on the landing gear! A RV and semi trailer are built totally different and your RV frame can't take the stress of this tug test with all the weight on the landing gear! The frame cracking is a result of owner error and not manufacturer! If you need to do the tug test on your hitch then you need to raise the jacks until they non longer have weight on them!

Interesting statement. This post was created to gather facts and see if we could see some commonalities to form an accurate hypothesis. Have you talked with the people that have had frame issues and have first hand knowledge that they in fact all did pull tests with the front landing gear down?
I like to deal in facts and not speculations, but that’s just me.
That would be awesome if they all did that as it could be a contributing factor. I would think you would get more front landing gear damage. As they were designed to support vertical load not horizontal shear force.
You should update your profile from still looking to what DRV you have. I’m assuming this from another post that you just made with in a couple of days.

Interesting theory cowboy. What is your source for the information to back that?

Yes ,I do a TUG test every time , BUT the landing gear is ALLWAYS up and the 5w is loaded on the kingpin ! I think most of this group would do it that way as compared to the way you described . And at least two dozen units have FAILED, if not more and I believe that it is a combination of DESIGN , MATERIAL , LACK of WORKMANSHIP and QC .I was sold a unit DESIGNED for FULL TIME living and TRAVELLING , but after 7 years on the road I do not believe that anymore

Pull test theory does not hold water. What does is the fact every failure has been towed with a non up and down absorbing hitch and kingpin.

I have factory rear air ride on my truck plus a TrailAir pinbox with an absorbing air bag. THIS is why MY frame has not failed as I have 6k pin weight like ARCliz.

Cracked frame tracking data

I do a tug test every time also - old habit from driving tractor/trailer. I do it with the landing gear down because I don’t want the trailer falling down on to my truck or falling all the way down to the ground. I fully engage the trailer brakes and give it a light tug. With all six hydraulic brakes activated, the trailer will not want to move and you won’t stress your landing gear. A light tug is all that is needed. It’s a good idea to leave your tailgate down while doing this (if you have one).

If you do a tug test and crack your frame, rip your landing gear off or drop your trailer, you might want to re-evaluate your process.

B&W hitch never do a pull test. I do a Visual test. Kingpin plate and 5er hitch plate touching, the hitch jaws wrapped around kingpin and hitch handle locked it is "HITCHED" no question.

Ron, in my opinion those ridiculing you have NO idea just how the B & W hitch operates! When the handle swings into the closed/locked position (with the safety pin in place) AND visibly you can see the jaws are wrapped around the king pin, THERE IS NO WAY YOU CAN "DROP" THE TRAILER!

I've had the B &W hitch for 8 years now and have NEVER come close to a "dropped" trailer, I might add like you, I don't do pull tests either, never have!

Dan

I took the morryde pin box off and replaced it with a Gen Y fifth wheel pin box. It matched up with a Trailersaver BD5 F.
Best investment I ever made

I would like to know why it's so good? I thought the TrailerSaver had air bags for up and down absorption??? I thought the MorRyde had fore and aft absorption???

So with both I wonder what the Gen Y adds to the equation.

Not sure why. You can clearly see when the jaws are around the king pin.

I’m trying to gather data to see if we can find a production range that has problems and if there are certain models that are more prone.

Thanks for participating.

Sorry this happened to you and thanks for the information. I contacted the admin to get this added to the list.

Met another DRVer today and had to break the news that he had a cracked frame. He has a 2016 unit also. It’s getting old breaking bad news to people.
