we had a 2004 Silverado. couple of other things to check
1) make sure ALL the interior lights are off. It's amazingly easy to accidentally turn on one of the front or rear overhead lights and not realize it.
2) IIRC not all the 12V outlets turn off with ignition so make sure you don't have anything plugged into the outlets
3) Double check that the visor lights are off. Again, another easy one to accidentally leave on.
Once the Silverado goes into full sleep mode, current draw should be in the few 10's of milliamp range IIRC. But on initial shutoff it can be 1/2 to 1 A.
Lastly, on the diesel, the battery power to the trailer plugs is ALWAYS on, even with ignition off. I don't know if that is the case on the gas or not, and it may depend if you have the one battery or two battery option on the gas engine. So if you have anything hooked to the trailer plug, I'd disconnect and see if the problem goes away.
