Yes, the battery should be tested. There is no advanced charging management on a 2001. But we -- that includes you -- don't know what the full amp draw is; measurements were given on only one circuit. Other circuits could be active.

tow mode raises the voltage

It has an aftermarket radio that i wired using a PAC OEM-1 device. This is his second aftermarket HU. He thought the first one might be bad.
Rap? Something else to look up and track down *sigh*

Battery has been replaced several times. Alternator is new. Battery was tested last week. The charging system is working like it should..

Only the radio amp fuse was showing a constant current draw. Every single fuse in the engine bay fuse block read 0
you must be using more then 215ma
if it goes dead in 2 days that is more like 3amp draw there must be a short somewhere low amperage shorts can happen but at 3amps it sounds like someone left the lights on..
Retained accessory power (RAP) is a power mode that permits the operation of some accessories for up to 10 minutes after the ignition switch is turned OFF. The RAP power mode is enabled by the body control module (BCM).
EDIT: this is why I asked if, after turning off the key, the radio and interior lights turn off when one opens the door. They should turn off.
200+ma is still too much to be right. I'm not saying it will draw down the battery overnight but it's at least 4x what it should be, unless I'm missing something else that's connected. Is there an alarm system on the truck?
It will be interesting to see what you measure for total draw on the battery cable with the inductive clamp.

Just plain WRONG.
It's a 2001 and doesn't have the RVC (Regulated Voltage Control) system that was introduced in 2005. So his Tow/Haul mode doesn't inactivate RVC.
it does not matter the radio "always" has power to it.. there is no ACC power on, on new after market radios you have to run a new ACC on power on wire to the new radio.. at lest that is what the W-body(the stock radios were pretty similar looking anyways to the GMT800s ) (my GMT800 did this as well 2004 and 2006,2000 i had driven)
on the stock radio as soon as you open the door you could hear a hissing noise from the amp( if you have good enough hearing) even the newer gmt900s do this in this case the Navi is loading the DVD and the amp turns on as well(slight hiss noise)

Of course it does or it would lose its memory. Duh. Some other modules draw a little, too, to retain critical settings, which is why a very small amount of power is always being used. That's normal and should be less than 50ma. In the PO's case, there is too much being drawn.
