It is a nice box for the money. I had one for a few days but didn't work with the power tonneau I installed so I sent it back.
The enclosure is the same size for the 10, 12 and 15 inch subs. It sticks up about 12 inches off back of baffle board.
He (Caraudiofactory) is currently working on a new one for the pioneer slim woofers that only sticks up about 4 inches. Caraudiofactory indicates they should have pics of it on the site in the next couple of days. My nephew has the pioneer slims and said it sounded like poo until he got the amp tuned to the woofer (it sounds like he got the woofer tuned to the box and then got the amp gain adjusted correctly but that's not how he tells it. . . ) Now that its set up it sounds pretty good. Not anything like a big box 12, but good for a slim line. If I had the room, I would go with the poly slot 12 box again.
No glass storage and it's not exactly light. flopping the midgate down is a finger cruncher if your not careful. The box narrowly cleared the glass on mine. I have heard others say it didn't clear and some say it cleared easily. There are different versions of this same box (square holes, ported, sealed, ect. ) so I chalked the comments up to box differences.
Anyway, that's my 2 cents worth (in a 50 cent blurp. . . )
