I am currently looking at picking up a 2011 reg cab, and was wondering how little room there is behind the seat. I have two 10's in my current system, and would like to move them into the truck. Does a standard 'truck box' fit, or do I need to go custom? Does anyone have measurements for a custom enclosure?

Before you guys tell me to just buy an extended cab or SCrew, I am trying to keep the length (and payment ) down.

 

Got a box from music moose for my regular cab

 

From what I remember when looking at single cabs, there's a TON of room. More than the 97-03s.

 

Yeah. I test drove one on Friday, and was amazed at the space behind the seat. I swear I could probably get the box from my Mustang in there.
