Sorry Guys - OP here.

The trailer is in Santa Fe, NM and I'm in Denver - so I have to plan a road trip down to the storage facility to review what's going on with the pinbox (and thank you for clarification on the correct terminology).

There's been some questions.
1. No, I didn't adjust the connection between the Kingpin (Spindle) and the Pinbox -
2. I've not had a chance to drive down (it's 400 miles) and peel back the plastic (under side around the front compartment and the nose above to get a look at it.
3. Under my bed is all covered in "quality" carpet. But it's a good idea to remove all the wood above the area if they are going to be welding.
4. I reached out to my bro in law who works for an insurance company. Had the nose crashed into the bed and bent it, the bed of the truck, and the trailer would have been covered - since the trailer is considered to be part of the truck - not a separate rider on the insurance polcy - and before someone recommends letting it - It's just not who I am. For someone else, that's an option but it's just my karma.

Depending on the weather (it's not supposed to snow here, but the weather is reporting 5" of snow between here and Santa Fe - but not in Santa Fe - so we'll see how the road trip goes.

My guess is that it will be another week before i go down to peel it all back and assess the damage.

Next will be looking for a quality welder in the greater Santa Fe area.

My alternatives are limited - I could tow it to denver - but how would I get it on a trailer? I don't have enough clearance to back it in. I guess a forklift could do it.

Again, thanks to all of you for your suggestions. It's this place that has helped me over the years and the community has made these types of problems, manageable!

A couple of years ago I noticed our pin box had been moving forward and back just a little by looking at the fiberglass joint just forward of the pin box area. None of the supporting structure actually bent permanently, but it had been flexing enough to identify a problem. Ultimately I cut out the fiberglass overhang at the front corners, roughly 4' x 4' with a 4" cut off wheel. I added about 250 lbs of 1/4" thick angle iron, and constructed some gussets for the corners where the pin box receiver is located. I decided to bolt everything in with grade 8 instead of welding. I had been carrying too much weight (tools) in the front area of the 5th wheel which caused the issue, plus double towing from time to time.

So if you have your trailer frame re-welded, I would suggest you add to that with some extra steel to strengthen the entire structure.

When I reinstalled the fiberglass panels, I made "L" brackets that allowed me to have threaded holes to attach the panels. Then I used stainless screws and covered the seams with 2" x 1/8" thick aluminum strapping. I also added new insulation and used the aluminum strapping to create a tight (read mouse proof) seal around the pin box.

We have an older Carriage triple axle, and also from Denver. We use a storage facility in the Southern part of Denver metro.

Good luck

OP and anyone else experiencing these failures should be filing complaints with NTSB. It's a road safety hazard and does pay attention to a developing pattern, and could issue a recall.

Like many others he will find broken beams and structure, and some welds that let go. From OP profile trailer is 2010 Keystone Cougar 244RLS(I now see that he had that in his original post), so I would be surprised if Lippert helps him. 10 year old trailer looking at 4-5K repair. And it is 400 away, and he is paying storage. Not good! Chris

DOT / NHTSA can be contacted at (888)327-4236 reference #11267716 and tell them you also have a similar failure with an LCI frame. Add your failure to the list and we can get results from an investigation.
My 27' toy hauler has I beam crack 9' on both sides, which allowed the axles to move around under trailer while traveling thru the mountains with my family. The CHP said they woul have been picking us up in pieces if we had continued to the next set of turns. I had LCI and Eclipse RV Manufacturing pay the bill to weld up and get us on the road home, but the next time we went to use it, the A-frame broke apart and was ready to completely fail, which would have been catastrophic. LCI sent an employee in an LCI truck to my business to weld that up too. This caused a lot of other damages to the trailer that they both said they would take care of after they got a dealer estimate, but nothing but crickets since!!!
They need to be taken down to the woodshed and taught a lesson, so lets get as many people to get on board with this to make things right!

Sorry for the long lapse between updates, but between the weather between Denver and Santa Fe, NM and covad, it's been a challenge getting back.

I went back the beginning of March, and peeled back the front and found the damage. It's pretty extensive. The pictures I took are not very good.

On another board, I found a similar failure so I'll be reaching out to the 800 number that Aboatrguy posted above.

As best I can figure it out, on highway 40 where the road goes up and down (whipping) it must have caused the pinbox area welds to fail. I think the perimeter welds in the corners (drivers and passenger) failed first (I think they were the weakest welds) and then everying else just collapsed in.

What I didn't see was the welds internally fail - just the perimeter welds. The welds close to the pinbox were solid and it was metal failure not poor welding that was the root cause.

I'm now starting to look for a welder in Santa Fe - so if anybody can recommend one, that would be very helpful. I know i'm going to have to peel everying back outside, but what's not clear is how much I need to remove on the inside to give the welder access from above to really weld this correctly so it doesn't fail, again.

If I was going to try and place blame, I would think the following combination:
1. My new truck (F350) has a stiffer suspension than my 2003 chevy 250.
2. there was more weight than we've had in teh past on the pin - meaning, we had a bunch of pictures and other breakables around the bed over the pin. In the past, we just have the normal clothing and blankets but not 'extras'.
3. The highway had serious drop outs or as we call them on dirt bikes Whoops that you really can't see until you feel them. I'm thinking one of them in NM somewhere before santa fe was the one that did it in.

the good news is once I do this, it'll be better than OEM. Now to find the welder.

Suggestions?

Thanks
Josh
