Your truck sounds very similar to my neighbor's which he bought earlier this year, a 'new' 2018 Sierra work truck, but like yours had many options for a work truck. His has the 5.3 V8 and 2WD though. Vinyl seats, not sure about carpet. I'd be fine without carpet like my first truck, a 1980 Dodge D100. In fact I just vacuumed out my truck, would have been nice just to sweep it clean. I guess a manual transmission truck isn't as pleasurable to drive as a short throw transmission car with an easy clutch, especially in traffic. Plus, these days the automatics with 6 speeds or more end up returning better fuel economy than standards. I was surprised how trucks only about 10 years old can have so much rust. My son's 2009 Dodge Ram has quite a bit already, more than my 2002 Silverado.
