Starting troubles

I have a 2015 1794. Recently I have been having some strange starting problems. Initially, the truck was dead, so I replaced the battery. I put in the new battery and went to start it and only heard rapid clicking. Trickle charged the battery overnight and it started right up in the morning. After sitting for a few days, the truck will randomly exhibit the initial clicking upon startup if the voltage (truck gauge) is just below 12V. When I get a jump it will fire right up when it goes above 12V. My thoughts are 1) I have a voltage leak and/or 2) my starter is going. Has anyone else experienced this?

 

This is a parasitic draw issue, the rapid clicking is more related to the battery. The starter will give you a single click and nothing else really besides thinking your truck is dead then resurrected as if it been hit with an AED, but starter usually goes out around +/-210Kmiles. Look up youtube videos on using a volti-meter and pull fuses until you see the voltage drop.
