Its a 2003 Silverado 2500 (not a HD) with the 6.0L LQ4 V8 and 4L80E transmission. Has around 280k miles on it and I got it for $1,500 from a friend's tow yard. Has the 9.5" 14bolt rear which is disappointing, but I can deal with it. Both the front and rear bumpers are a bit derpy and need to be replaced. Interior is rough, already tossed the sub and amp that were draining the battery. Lots of little things like no battery hold down wedge doohickey, a broken tailgate handle, broken passenger key cylinder, and a passenger mirror hanging on for dear life. No rust underneath, just a leaking diff and probably a bad water pump. The coolant reservoir was empty and when I filled it there was a leak from the front of the engine. There was a new Gates water pump in the bed so I might as well put that on. Already ordered a bunch of little things to fix the truck.
