I had the same parasitic drain issue with my 2005 LT. What I did was cleaned my battery cables and replaced the battery rundown protection relay ( located on my LT in the passenger side fuse block ). Idk if it was just a loose/corroded batty cable or relay but after I done that I haven’t anymore battery drains. Hope this helps.
