Truck has power lights and everything work but as soon as I go to turn the key i get a click and all the dash lights and interior lights go away.

 

Slight update I was able to get the truck out of the dt bank parking and back home so that was good. I pulled the rear most spark plug on both sides they looked clean then i disconnected the battery negative then positive and put them back on truck started right up. Any ideas on the cause of why this worked or what needs to be fixed.

 

That is what got you back up and running, check all the batt ends, then all the grounds. Clean and or replace cable ends, batt terminals.

 

Thanks makes sense.
