1975 31' Main BeamFrame Rust

Hello Everyone,

I've taken some pictures of our frame here, based on my research on the forum it looks like I should be basically cutting out the section in the photos labeled A and replacing it. I am still unsure how I would go about replacing it, and would appreciate some input.

Beyond that, I think the photo labeled B can be patched with a doubler plate and the I am unsure what to do about the area labeled C. As you can see from the zoom in the rust has many layers to it.

How much trouble am I in here? I've included a shot down the line of the trailer, and it does not appear to sag (side bath model) which is encouraging.

So is the shell still completely attached to the frame (all bolts from outriggers up into C-channel still in place)? If so, one reason it doesn't appear to sag is that it is still attached to the shell, and the shell is holding the frame up.

I would invite a mobile welding service to come and assess the frame, especially one that builds or repairs trailers. They ought to know how to go about doing the needed work, and evaluating whether something just looks bad, or if it is cancerous and needs to be cut out and replaced.

good luck!

Thats a good point, the shell is still attached near the rear, which may be holding it up. Many of the bolts have failed but I would gather there are probably 10 or so in place near the rear. Pretty crazy think that the c channel never mind the bolts is holding up the back of the trailer.

Good idea about the mobile welder. I hate existing in the limbo where I just don't know enough about this stuff to make a decision.
