I think certain models are only made in Mexico, so depending on what you want to buy that could factor in to your decision.
I have had my 2020 Silverado 1500 RST Z71 diesel for just 1 week and I have no complaints so far. Not much of a sample size, I know. I drove a 2010 Tundra CrewMax (manufactured in Texas) for 10 years before this so I am appreciating some of the newer features and refinement of a new truck.
I had a 2000 Silverado 1500 many years ago, and I believe that was manufactured in Ontario, Canada. It really is a global marketplace. I can understand your loyalty to American-made but I am willing to bet the clothes on your back and the shoes on your feet were made overseas. If you find the truck that you really like, I would not let the place of manufacture cloud your decision making.
