I really wanted the 38 gallon tank but I actually prefer the bench seat/column shifter to the buckets/console shifter.
I have a couple small kids and when we hit the dirt roads they like to be up front with me.
It also allows me and my son to sleep in the cab, one on each row, on quick camping/hunting trips.
Crazy, I know, but it was also cheaper than the upgrade package that includes the 38 gal tank.
