Our first YJ was named Lazarus as we raised it from the dead.
The unofficial name of our current YJ is "Ed" because it's maroon with a tan top, tan rock slides and tan fender flares (Eddie Bauer - esc). Not sure how the name's gonna stick though. My wife just calls it The Jeep. Which is odd because my son has a ZJ which she calls the Cherokee.

Interesting thread. I have never named any of my trucks/cars. All of my Harleys were named after female names in Grateful Dead songs. One of my Sportsters was Delilah, the other was Althea, and my Softail was Bertha, but I never even thought about naming the Jeep- it always seemed like a Motorcycle thing to me. I dunno, maybe I'll give it some thought.......
From an old Navy Senior Chief when I called him sir- "Son, don't call me SIR! I knew who my Father was!"
