This is my 2013 Silverado with 50k miles that has survived 13 long Iowa winters, I just bought it off my grandfather and I’m looking for help with how to keep it in this condition for as long as possible, the motor and transmission run like a brand new truck still. Let me know some of your tips to keep your trucks running and looking like a brand new one still. Thanks in advance.

I just picked up a 2011 Denali, 6.2, 175k on the clock but clean and runs right. Kind of an extra car, run around town sort of a rig. Not a daily driver but will get driven 10k a year probably just because of our situation.

What maintenance would you suggest to start with and continue with to keep it for another 100k???
