Part of any successful trip, is keeping the children happy and entertained.
On that note, the latest addition to the overlanding rig is a "movie theatre". The kids seem to enjoy it quite a lot, and the entire setup adds less than 6lbs to the camping gear! Sure its not Hollywood quality, but the portability and low power consumption is perfect.
Here is the setup, the screen is hanging from my rear awning (it needs ironed out still)
-Ozark trails 100" projector screen
-Miroir M75 DLP micro projector (runs 2 hours on a charge)
-Usb to HDMI adapter
-Cell phone with Netflix subscription
-Battery powered Memorex speaker
