Since we boondock pretty often I was uneasy not being able to monitor the voltage on the batteries. I brought this LED voltage monitor at Wal-Mart (about $16) and plugged it into the 12 volt receptacle in the stereo compartment. One more thing to keep an eye on while watching DVD's and running TV, computers, etc. from a 12 volt Inverter.
