Plano 1812 box

I test fitted a Plano 1612 in the Ultra 4.3 trunk area behind seat, and there seems to be some space around it.  Would the next size up box, 1812 fit?

update:  next size up fits, but it's so freakin' huge, i returned it.  reverted back to my old plano ammo box instead.

LOL, the 1812 fits in my Adventure and I love it.
