Our 2008 Shamrock had the old style latches which seemed more substantial. The new style are much easier to use, but threw us at first as looking "just barely hanging on" as you mentioned. When we were closing up after every trip last year DW would look at the latches and ask, "does that look right to you?" Kind of hoping she now has that out of her system(LOL).
