As Sarge Green is apparently not an option I would have to say Sting Gray. As I have a 2020 Sarge Green JLUD I am kind of glad that it's not offered, sorry
Recently purchased a 2020 JLUD in Sarge Green w/Black soft top and interior. Loving it. Will post pic's when I get a chance. Waited a long time for the Diesel in the right color. No regrets for waiting.
