MK, im assuming its because your tc is 7.25' instead of 8' . The jacks can't spread out far enough for a dually.
Being that the tc is only up in the air for a short time, to load and unload, i don't think the amount of added stress will make a difference.
If it were my tc and i knew the corners were solid , i would extend the brackets to gain the extra width. But i would leave it on the truck and not take it on/off unless i had to. Minimize the stress.
You must be a pro at this , I would have knocked it over by now .
