if your not driving it for more the 3-4 days be sure to turn off the auto key function at the bottom of the steering colum left button this will help the aux battery stay charged longer. for winter storage or a long trip you should pull the radio fuse from the under the hood fuse box to stop all draw on the aux battery. the other thing weve seen is the light for the cargo area can be switched on and forgotten about because you can't see it with the hatch closed.
