I'm finalizing my hatch design and I like the clean look on the hatch. I am leaning towards using internal latch pins on both sides tied to the T Handle in the center of the hatch. I see a lot of folks with external latches and I'm wondering if there are advantages to one way or the other...
To me, internal is cleaner but if something goes wrong the latch mechanism is inside the hatch. External seems easier to implement as well.
Other then this, does one way work better then the other as far as sealing of the hatch from dirt or rain?
