It's a bigger pain on the 5th gen trucks. I did this back in February on my 19 laramie.
You will need to pull the entire grill to remove the letters from the back. Screws and clips are holding the letter assy in place.
Definitely look for youtube videos on the removal.
If you have factory fender flares, you should plan on removing those to get at the one bolt between the fender and lower piece below the headlight 7mm or 8mm socket eureka well for popping the clips lose from the back .... No one mentioned it in their videos that I saw and I had no plans on breaking anything to get it apart.
