Hello, my 2009 4.0 was parked for 9 days with two chargers plugged into the dash and the battery was completely drained! I've got jumpers and will get it going as soon as my girl friend gets home. I was surprised that they took so much juice. One was a phone charger that wasn't hooked up and the other was charging the battery in a GPS unit.
I guess I won't do that again!

Future mods: roof rack to carry a kayak or two
not sure about others - maybe some exhaust mods that won't mess with Cali emissions.
