I have the Otterbox for my Sprint Tab 3 7.0 and the cover converts to a stand. Coolest thing is that my Durango (2013) has a small space under the radio/navi screen and climate controls and the front cover/stand fits perfectly in it. So I have my tablet sitting directly in the dash, securely angled toward me. No movement or anything. It's meant to sit an angle in the cover - maybe 40 degrees, but the opposite side has the ability to hold the tablet up perfectly straight. It's weighted well enough that it won't tip over if sitting on a flat service.
Got it for $29 on Amazon.
