If just pulling the everplast off damages the frame then for sure he'll want to inspect it.

I would nor know if I was looking at a bad weld or not.My neighbor across the street is a certfied welder for a large company and he said the welds that he could see were Ok in his opinion.

It is not a bad idea to look if it makes you feel better but make sure you have a qualified person give the opinion.

I would start out with looking at the tag with the GVWR of your Rv then weighing it since RVSEF has data that indicated that over 65% of the Rv's they weigh are over weight.That would be just to make sure that running overweight is not a factor in any frame issue.

There is another item on these frame problems, it has to do with the hitch you are using we had a RBW hitch that only rocked for and aft, we got into a bind backing in, trailer really twisted and we heard the frame break at the pin box, my fault, swithed to another hitch that rocks for and aft and side to side, can back in know with out binding up the trailer and no further problems

Here's a way to see a problem without taking apart the front overhang area.

Watch for movement of the pinbox in relation to the skin as you raise the front landing gear when hitching - movement at the point where the weight is transferred to the pin could indicate a problem.

Have someone inside the closet in the nose of the overhang while hitching and unhitching (raising and lowereing the front landing legs). Pay attention to the corners and closet walls for any sign of movement.

Any movement in these areas probably would indicate a pinbox frame problem.

Only a certified welding inspector would be able to determine the faults in a weld. Just because it looks ugly doesn't mean it won't hold and just because it is pretty doesn't mean it has correct penetration. Just throwing in gussets to stiffen things up is a bad idea because the frame has to be able to flex. It would also be really easy to set your trailer on fire while fixing something that ain't broke.

Without the ability to flex the frame will break. Rather than inspect and reinforce the welds I suggest you test them on a rough section of hiway. If it doesn't break you are ok.

I have a 2005 Cougar with a Lippert frame. I'm considering taking down the vinyl on the underside of the overhang to expose the whole king pin and all the welds. My thinking is to have a weld shop inspect and reinforce anything that might look weak. My question is, has anyone taken down the vinyl? How tough is it to do? Is it something I can do in the driveway? Thanks for any input folks.


If you have a symptom that something is wrong. It's a good idea. However if you talking preventative maintenance, or going through the trouble based on the forums or some story of some sort I would not bother.
If you inspect it today how do you know it won't break tomorrow?
Where does it end?

Basically instead of building up the weld as your proceed, the welder just drags it backwards like spreading caulk.

Wow, so much of that post is just wrong. No, you don't have to be "certified" to tell a bad weld. Minimal experience and training will tell you that much. And no, a frame shouldn't break because it doesn't flex much. Frames of cars, trucks and trailers are made stiffer all the time and it doesn't result in breakage. To the contrary, there are fewer fractures. Finally, ugly, yes, you (or someone who knows what they're looking at) can easily see a bad weld. A good weld is never "ugly" to someone who knows what they're looking at.
