Power Draining In Nbs Sierra

[whitejb3]

I have a new 2007 GMC Sierra I don't drive but a couple times a week. I recently tried starting it and it was completely dead. I have charged battery drove it around fine but when it sits for more than two days the battery is completely drained.I have taken it to the dealership and everything checked out ok after a overnight stay there. I have a aftermarket radio with the correct wiring harness also fog lamp I have disconnected and the problem still occurs any suggestion would be much appreciated
