The Model AA was a workhorse that could wear many different bodies. Here is a tour of nine examples, from simple cargo haulers to buses and fire engines. The same sturdy truck could be adapted for a remarkable range of jobs. Click any photograph for its original source and full credit.
Pickup / express body
An open cargo box makes this AA useful for smaller loads and everyday delivery.

Dump truck
A tipping body put the AA to work hauling dirt, gravel, and other loose material.

The AA also served communities as a fire apparatus.
