I have cracks just like that on mine....except mine are a matching pair right and left, inside and out.....previous owner told me it happened when somebody broke into his cuddy years ago and kicked in his door. I ground them out a little , filled them with epoxy resin and then had a new ss threshold made up that extended out to cover the cracks on the outsides.....I'll post a pic later...let me know if you want to do the same...i bet the dimensions are identical i could bend one up and send it down to you. I think it does look a little like a patch of sorts but it definitely looks better than what it would have turned out like if i tried to hide it with gelcoat or paint.
