I have many add-ons to my 6.7 turbo diesel. Just wondering if my constant battery drain is related to these or another problem that is fixable? Currently if I dont run for 3 days then my truck (with new batteries) will be dead. I have to keep on a battery tender even in the summer to start when I need it.
add-ons are
1-After market bumpers with builtin wench
2-Automatic side steps, open when door opens
3-Custom audio system (2-1000watt amps)
