Is this a usual place for a frame to break ?

In a word.... Yep. It has also been seen in a few 16' Scamps hereabouts.
I reinforced that area on my Hunter long ago in anticipation of that issue.


That looks like it has been compromised for a while and I suspect that it was spray-canned over to hide the rust.

Looking at those pics, I would GREATLY question the integrity of the rest of the frame! Just be thankful that didnt happen while pulling out on a busy road somewhere!

It wasn't mine but a friend of mines trillium outside of Langley B.C ...
Think I will be doing some preventative maintenance on mine right away

Looks like you have your work cut out for you.....

I wasn't there to check it out when he bought it ...but I will be there to fix it

Just a note of caution regarding frame strengthening. My brother had a frame member fail on the tongue of his old stick built. When he approached a professional welder to fix it for him, the welder noted that you have to be really careful about strengthening where it broke, because if youy make it too stiff, it may prevent the frame from flexing as a whole and concentrate undue stress in another area causing another failure.

That is exactly where the Trillium recall requires a couple of reinforcement plates to be welded. This is clearly missing on this trailer.

Below are a couple of drawings, I did, that detail the reinforcements that are used on a 4500 frame. Note the taper at each end. This reduces stress from too much stiffness. Note these plates are on the inside and outside of the square tube.

The Scamps tend to break on the left side because the right side is weak under the door opening.
the under the door tubes tebd to break at the reinforcements as well letting the right side flex even more and increasing the stress on the left even more.

Can you all give some information about 1974 Trillium 1300 frames? Any known problems, recalls, fixes? Where can I find that out?
I frequently travel on pitted dirt roads that must push/pull the frame a lot. Have wondered and worried about this problem!
Thanks for your input.

Anne, I am not sure why, but the recall info seems to have been removed. As I understand it, it was for their 1300 model, 1973 to 1976 only. I have seen a number of different fixes, since Trillium did not do them all. Many were done at private garages. I would go with what Trillium did on the 4500's, as shown in the drawings above.

Thanks David! That puts my Trillium smack in the middle. Luckily, I found a great welding shop, they love challenges! I will show them your drawings and hope they can do it before vacation...
