This was my first attempt for my wife. It was an XL but short of replacing the 5.3 everything had been done. Bracks, interior, stereo, suspension and wheels. It was a LQ9, TVS1900, and 2600 stall from being perfect. I was able to tow with this one so maybe I can air up the bags on the new one once loaded and tow the Trailblazer or Silverado to an event or race
