I removed the battery because leegreen said it could have a short. Never ran into that before and it came off the shelf fully charged but its an easy test. It stayed fully charged. Battery test complete.

I disconnected the alternator. The battery still died overnight. So its not the alternator. Alternator checks out.

There isn’t a radio or any lights hooked up (or even in the truck) so its not that stuff.

I appreciate the suggestions
