Just bought a 2004 Yukon XL 2500

Very nice rig. You bought the twin to my rig (aside from color) 2004 Yukon XL K2500 8.1 with 4.10’s. I bought mine with 178k miles also and nearly the same shape. They are a diamond in the rough. I spent over a year to find ours. Nice find! They are amazing rigs. Enjoy!- BigDogYJ

Probably pretty rare. My 2004 Yukon XL is powered by a 2006 LBZ Duramax and 6spd Allison. Also has some upgraded front end upgrades and bumpers. Sent from my iPhone using Tapatalk Pro- BigDogYJ
