Mine need a 5x8 foot hole if I remember right ... ;-}
... and ya ... that is a MaxxAir fan, and measures 14x14. One word of caution - put the remote in a safe place as the built in control panel sucks ... not a bad idea to add the batteries for that to your annual list of things to do.
PS - if the type two's are anything like my 2011, there's only one support rib between the front and rear doors. You can see where mine was cut out for the pop top.
