Greetings all.

I got a new truck - and a new hitch - thanks to you all for your opinions.

Hooked up the new hitch and the trailer and the world looked good - after some height adjustment.

Things looked good. Until tonight.
As I pulled into Santa Fe on my way back to Denver, I was looking in the rear view mirror and thought the spacing between the bed and the bottom of the 5er was small. So I Pulled into the Motel and stepped back. The entire kingpin looks like it's bent upwards - and had actually bent the front fiberglass nose of the 5er.

I've never seen (let alone heard of) something like this.

Tomorrow I can raise the hitch up - but I don't think that's going to stop the collapse of the kingpin into the nose and eventually it'll hit the bed of the truck.

I have no idea what I'm looking at - if I can risk the 400 miles to Denver.

Since I've never disassembled the plastic around the tongue to figure out what's behind it, I have no idea what i'm getting into (and won't until tomorrow.

It's a Lippert chassis - cougar 244rls 2010

Thanks in advance!

If it were me, I wouldn't go any further until I knew the extent of the problem. It sounds very much like the frame is flexing and bending under the covering in the nose. Either broken welds, or broken frame. You should be able to remove the lower covering and see the issue. But much moving anywhere is going to make it worse.

There are a lot of documented Lippert frame issues. It sounds like you have a frame failure that many others have experienced and that will require extensive repair and reinforcement. Do a quick search on Lippert frame failures and you’ll have hours of reading to keep you company.

Whatever you do, do not tow it until it is inspected.

Yep. Frame failure, for sure. Leave it there or put it on a lowboy to bring back to CO to a =good= welding shop that has RV repair experience. Going to have to unskin the front and have the frame repaired and beefed up. Keystone and LCI will just say "so solly". Whatever you do, don't tow it! You could try filing an insurance claim, but they'll almost certainly say it's a manufacturer's defect (which it absolutely is) and won't cover it, but you could try.

Like the other posts, somethings broke and it is not safe to operate. Inspect it and find a good weld shop to do the repair work.

Like others have said, frame issue. Just a side note, it will help when explaining to others if you know the correct terminology. Your "Pin Box" is moving up into the front of the trailer. The "King Pin" is just the part that latches into the hitch. Good luck with the fix.

I would stay put like everyone else has stated... I would have to bet on frame failure just by what you have described..

Good point.
Its rare a pin can be bent but it does happen with heavy OTR rigs and aggressive operators.

Its also rare the pin box is bent on a rv trailer.

What not rare at all is the sub frame where the pin box is attached to the trailer frame gives way for various reasons .
I had this issue with my current trailer in '03 and its not a Lippert made frame.
The fix was normal and was done under a extended warranty plan. The dealer dropped the filon under side.
Then added bracing/modifications/type and size structural materials to my satisfaction and recommendations. Buttoned up the filon under belly.
That was in '03 and 130k-140k miles ago and no issues.

Thanks everybody for the quick replies.

I'm going to raise the hitch height to get the clearance I need to get it to storage and then begin the process of working with lippert and the insurance company to figure out what are the next steps.

I'm close enough that when I need to open up the front to take pictures - I can drive down and back in the same day, get the photos I'm sure they are going to want and go from there.

I will tell you that I don't exceed the tire rating on my 5er. I've had too many years of blow outs to know that going faster than the tire speed rating ends up badly (Blowouts).

The only thing I can think of is fatigue or poor welding and the factory and the welds finally failed. The New Mexico roads had quite a few "bumps" in the road and I'm sure that the whipping motion was more than the welds could take.

Again, Thanks to all!

Seriously doubt metal fatigue and put my money on inadequate engineering, inadequate materials and just plain cr@ppy build by LCI.
