In 2009 I had a set of "EZ Hitch" that had the same problem that the above PATS has. The company rep said that I could saw that top interference off, as it would then slip in there. Well that would defeat the usability of the EZ Hitch with other implements. So I just manually hooked up the box , since it was empty and not too heavy at that point. Now with the Quick Hitch I do the same thing, but have to take the QH off.....:thumbdown: Fortunately, that doesn't happen that often. Hope this helps.
Cheers,
Mike
