Never had a nickname for my X, but just recently I took my wife to Big Bend National Park. I’ve been there several times, but this was her first time. As we just started heading down the back country roads, we got on the subject of nicknames for the X. She started off with “Hoss” but then quickly changed it to “Mule”. I asked her why, and she said because I was always loading the X down with all this equipment and heading down roads that only a mule would travel. Seemed very fitting, and even more so since most all of the back country roads in Big Bend started out as mule paths anyway… So henceforth, my Xterra is known as “Mule”.
