I got tired of having a truck payment (I've had one since 2005), and decided to sell my 2021 Sierra and buy a used truck for cash... NO MORE TRUCK PAYMENT!!! It is a 2006 Sierra 2500HD 4x4 with the 6.0L engine and 4l80 transmission. It had 143,000 miles on it when I bought it a month ago. It has a few things that I need to fix, but it runs well and I use it as my daily driver.
