I looked for 4 months to find exactly what I wanted 2 years 2 months ago, Red GMC CC/SB SLT, couldnt find what I wanted posted exactly what I was looking for on here and 9w3-HD found what I wanted not to far away from him in Colorado. $41,000 with 13,000 miles, lifted, step bars and topper, and that was when GM wasnt even making the diesels anymore between the LML and LMM so it was like they were dealing new ones.
Keep your search open if you have to go to the other side of the country to get a truck its worth it for the right truck and price at most a plane ticket and a couple tanks of fuel, I know I saved about $2,000-3,000 from anything I could find local, without the aftermarket parts and with trucks that had 40-60,000 miles.
That red twin everything LMM that was here in the classifieds a couple weeks back was the deal of the century on an LMM, it sold for what like $42 or 43? with a built engine.
