Looking for a 2500HD 8.1L Truck

[Born30YrsLate]

Not sure if this is the right place for this, didn't quite seem appropriate in the Supercar/Musclecar Wanted section.
I'm looking to replace my current truck and am looking for some help in locating the truck I am looking for. Since I live in the rust belt it's hard to find something rust free. So what I'm looking for is:
2004 - 2007 Sierra/Silverado 2500HD 4x4 with the 8.1L engine and Allison Transmission with ~125,000 +/- 25,000 miles.
Prefer White (will consider Black), prefer crew cab (will consider extended cab) but must be short bed, and be free of any notable rust.
I've been looking in the local area for a while and have come up empty, lotsa diesels or rust...I don't drive the truck enough to run the diesel as much as it should be...so I figured I'd ask the help of you guys in case you come across something.
Feel free to pm, email: faeichhorst(at)gmail.com or text me at 920-901-51O8 with any leads.
All help is appreciated!
