An example of a Federal Shitbox. LLV stands for Long Life Vehicle. 40+ years is definitely a long time.
Your mail wasn't delivered because another LLV caught fire.
A mail truck, generally an LLV or FFV. For those who work with them, they are absolute shitboxes. As they are federal vehicles, government money is the solution to all the problems of the Federal Shitbox unless the frame is bent.
Features of the Federal Shitbox include (but are not limited to):
-at least two bald tires
-fucked up alignment
-rear door jammed in the up or down position
