I did it on my first playthrough (which I understand was really weird). I started Lonesome Road at level 2, and then spent pretty much all the ammo I got taking out the Deathclaws (and even then it took multiple attempts).
I apparently did the DLC in reverse order (starting with Lonesome Road, then Blue Mountain Blues, and then the Sierra Madre), and never met a Ghoul until after finishing the game and backtracking with an older save.
