Parasitic Electrical Loss

My 4Runner is an 03 SR5 so it's pretty basic. It will sit for a week or more at a time as it's just for recreational use, but lately it's dead every time I go to start it up. The only deviation electrically from stock is the aftermarket stereo, but that was in for almost a year before this problem started

Has anyone else dealt with this? Any smoking guns in your case?

 

Parasitic drains are a pain in the arse. Had one on my 4runner and ultimately narrowed it down to the remote auto start. I disconnected it and that fixed my drain. Good luck man.
