It was a bit ago now but I remember being surprised by how much more stable the 14 felt compared to the 12 for just a couple (?) inches width wise difference.
Length wise, I think the two feet are all in the front hatch
. If you were to look in your vehicle right now what would you have? A clean empty vehicle because you have a garage and in that garage, a special place for everything? Or do you have an assortment of tools you're never sure you might need in a pinch, something or other you don't want to get rid of but don't know where to put it, that item you borrowed from who's its you'll give back the next time you run into them?
I can't imagine not having the big front hatch and I don't fish/have all the assorted fishing gear. I have an anchor, a throw line, a cap for evening trips, a brimmed hat for being in the sun, a water-resistant picnic blanket, a beach towel, I keep my clothes in there when swimming, a jacket if it gets cool...
14! 14!!! FOURTEEN!!!
