2011 Chevrolet Silverado 2500HD Z71 LTZ Duramax 15k in Upgrades

Truck is clean with normal wear for a 4 year old vehicle. I was building toward a turbo but have decided to sell and get a more practical family vehicle. We just had our fourth child and no longer fit in it. Here is a list of all the upgrades I have done. Stage 4 suncoast Allison transmission professionally installed by the best Duramax/Allison mechanic in 3 states. Paid $500020" RBP 94r rims with Cooper Discoverer A/T tires with good tread leftH&S MINI MAX PROGRAMMER WITH DPF DELETE5" exhaustS&B cold air intakeleveled 3" in front with Cognito A Arms Fox shocksBushwhacker fender flaresN-fab stepsLine x spray in BedlinerDual TVs in headrest with dvd in eachXm/Sirius installed Bluetooth phone and additional Bluetooth for streaming Audio installed. heated leather seats this truck is a Z71 LTZ but the fender flares covered the Z71 emblems so I removed them. I have new replacement decalsThere are a few scratches around the body that can easily be buffed out and there is a small ding in the bumper caused by trailer not collision (see pic). Never wrecked. Flawlessly maintained. I would consider it in excellent condition. It gets 22 mpg on the highway and has a ton of power. Never dyno'd but the tech that put the suncoast transmission in said it should be over 500hp. The transmission is "bullet proof" according to him and will pull just about anything you put behind it.
