Parasitic DRAIN? (Nissan Titan 4x4)

This 2004 Nissan Titan 4x4 drains its battery after sitting for about a week.
The owner is fed up with jump starting his truck, and brought it over for a diagnosis.
He said that his aftermarket remote start system stopped working some time ago, but is that our culprit?
The findings are surprising!
