I have the webcam mounted for my backup cam but am having some problems with it in the daylight so I might ditch it if I can't figure out a solution.
As far as reliability I drove 9 hours back to college with no freezes or hiccups. Since I made my hub externally powered the tablet get enough power to stay fully charged over long trips while using gps and screen brightness on full, but I should not have any problems with it staying charged with Timurs new USBROM that can enable fast charging.
I also have a few hidden buttons in my center console for the 3 tablet buttons and also a charge button to charge the tablet even when the car is off if the battery get low, for example its been below zero for the past week so my battery is probably extremely due to the extreme temperatures. I normally only lose 1-2% over night but since I haven't been driving my car these past couple of days I have lost ~20% in a 24hr period from the -10 degree temperatures we have had, which is when im glad i added a charge button so it can charge while i'm in the store or class or something.
Oh and for GPS and wifi antenna I ended up mounting above the headliner on the passenger side and ran wires to the connectors.
I'm currently using
-Timurs USBROM with kernel built in Link
-mediaU to stream local radio stations
-GMD Gesture Control
-Probably others that I am forgetting

Of course you can do this for much cheaper, since a nice chunk of that went into audio equipment and extra accessories.
4 channel amp
Bracket I made to mount the tablet to. I added a fan to help keep the tablet cool along with some velcro to mount the tablet to my bracket.
Had to add some wires for the power, volume up and down buttons that I ran to the center console in case the tablet freezes or something. Also had to run wires to the back cover since the wifi and gps are basically stickers on the back cover which I just velcroed to the top of the stereo opening.
