I want to avoid using the inverter. They're noisy and are a power draw. I am not on a network inside the bus. I have a 7 inch Android tablet mounted in the back of the camper and I'd like to have the Pi stream to the android device like a touch screen monitor. It would work like Plex but without having to run another server.
What I have:
Rasberry Pi 2
Wifi adapter
Bluetooth adapter
External drives
12 volt USB hub
I'd like to avoid using a monitor because I use the tablet for other things like weather, Skype, alarm clock etc. Thanks in advance for any helpful advice or ideas.

This is the beast it's going into.
