You might describe where on the trailer's frame these cracks are located. I think the savvy folks on this forum could give you best guesses on how to repair those cracks. Looks like a fairly simple fix where welder could brace over where the cracks happened. If we knew the location on the frame, there are those, as I said, who might be able to guess how it happened as well. Do you routinely pull that trailer over rough roads? Looks like you might be in Canada?
