the only solenoid in the truck would be the trunk lock solenoid for the trunk latch assembly if you open the trunk and unplug it will it still draw the battery down ?
these having draws like this can be alot of things
we have seen many things cause draws like this
hands down the 3 most big draws are the radio or gauge cluster or the BCM
there are 2 ways to go about this
doing a draw test with a meter and if the mili amp draw is over 50 pull one fuse at a time until the draw drops below 50 ma then what ever that fuse powers is the problem
OR unplug the radio and see if the battery still dies if not then the radio is bad and keep doing that with the electrical components starting with the radio
we have had a few with alternators and starters doing this so i would highly suggest a shop do a draw test so you do not guess on the issue if it still does this after you unplug the radio
