Can you elaborate on your tailgate dampener fix, please. I have a 2018 that I feel the dampener is not consistent. Have held off taking back to the dealer since some days the tailgate drops down firm, and other times is does exhibit some dampening action. My truck is 1.5 years old with just 8500 miles. Bought it to replace my previous 2012 that had 50k miles. It is a vast improvement over the 2012, especially how quiet the powertrain is.
