This might be a dumb question, but is 70k too many miles on a truck to invest in a goose tune and new live valve shocks and springs? I bought my 2019 new and love it. I'm trying to decide if it would be silly to spend $8k to upgrade it vs. buying a gen 3. I like the looks of my gen 2 more than the new ones. What do you all think? Pics for reference.
