I'm using a Galaxy Tab 2 7.0 WiFi Garnet Red GT-P3113 with Jelly Bean v4.2.2 (HOME_XAR_P3113UECMH2_1251263_REV04_user_low_ship.tar)
Note: Anything below that number can't move the install stuff over onto the SD Card though the Apps option. That option isn't there. Will be there on the Jelly Bean v4.2.2 and higher.
I have a 32GB SD Card.
I rooted my Android with CF-Auto-Root-espressowifi-espressowifiue-gtp3113.tar by using this Odin3 v3.07 tool.
After rooted my Android next update the SuperSU and then got the SuperSU Pro.
FolderMount [ROOT] full < Use this to move the rest of the games files onto the SD Card to free up more space. For example: obb and data.
I moved over ton of stuff over onto the SD Card.

Extras below.
I use the My Backup Pro to make back up a game installer (apk) or what ever. Better than the Titanium Backup PRO making a mess.
ROM Manager < Got the clockworkmod from it. I use this to erase everything from the Android and SD Card. So that I can use a fresh Android version on my devise without having to worrying about the old stuff still there.
Clean Master (Cleaner) < I use this for cleaning my Android up and free up memories.
BusyBox < Don't really need this. It is useful for copying through the USB onto the computer or what ever. I won't mess with this at all. I did once and deleted right off of my Android. I just seeing what it does.
