Good point. I would try disconnecting the ground cable in the dark. If you see a little spark when you hold it about 1/4" away from the post, you have a power drain somewhere. Check any thing you might have added. Backup lights, spotlight, electric winch?
Or disconnect the ground and leave the truck for 2 or 3 weeks and see if it holds a charge.
