Lippert "news" (?)

Interesting.

Maybe they are feeling the heat. But that's motorized stuff, not mention yet of the "cheap stuff", like fifths frames.
In the meantime Jason Lippert keeps enlarging his sand box.

I've gotta ask, "have you had an issue with the 12" or 10" Lippert I-beam frames?

Thanks for input in advance.

Not currently, the rig I have now doesn't have anything made or sold by Lippert, but this was my past experience.



The company that made that fifth certainly was buying their frames from somebody, wouldn't be surprised if it was from folks who Lippert owns now. For more "in depth" discussions of Lippert frames there are a couple of quite recent forums.

Another Lippert frame issue - HDT - Escapees Discussion Forum

Yet ANOTHER Lippert Frame Failure - HDT - Escapees Discussion Forum

I posted the topic because what Lippert is doing is actually a good news, somebody at Lippert is "noticing" and reacting. I spent my entire life in product development and manufacturing, large and small companies. I have no doubt that Lippert or the frame building subsidiary they purchased could build outstanding frames. It starts exactly with what they announced, properly training their employees and then have quality control people check on the work going out. And they should do one more thing, fire the idiots in charge of the subsidiary who couldn't think of those two things in the first place and created a public embarrassment about quality of Lippert frames (actually their own) in the marketplace.
From what I have seen the issue with Lippert frames is not the the use of 10" or 12" I-beam frames, the failures are poor welding in general and inadequate design and materials used around the pin box structure under the fifth overhang. Here's an example, although I don't know who made that frame.

There is a lot of stress on that weld where the two tubes come together in the front and the two rear pieces of steel might as well not be there.

Incidentally Lippert acquired their frame building subsidiary Quality Frames (?) in 2002, they had plenty of tome to straighten them out and improve quality.

LCI is owned by Drew Industries, which also owns Kenro Inc. Jason Lippert is CEO of all three companies. They just moved to Elkhart, IN and added ~500 new jobs.
Certifying their welders completes their end of building a quality frame. Now it's up to the trailer manufacturers to spec a quality frame, beginning with high-quality steel.
IMO, That broken tube in the picture is not a faulty weld, it's cheap steel that became embrittled from the welding process.

I agree with you wholeheartedly that the crack was a fatigue of an embrittled tubing because of wrong gauge, that stuff was paper thin 12 gauge at the most maybe even 14. The design wasn't bad, basically it was this

and if they went with tubing that was 3/16 wall it would have been plenty strong. The crack was in the rear tube going side to side and where the pin box tube was welded.
The right front corner crack was just a poor weld crack. I think it was either C, E, or G, take your pick.

Heavier tubing and proper welding would have done a trick on this corner.

If they "really wanted to do it right" perhaps something like this,

or this.

Although the last solution probably would get the manufacturing guy fired for wasting time and money.

I agree he's wasting time and money with the angle iron, but then I'm not a big fan of angle iron gussets, I'd concentrate on making a good butt weld between the two tubes all the way around (leaving a small hole on the underneath side for drainage) and then adding the two flat gussets just for good measure.
