* Dodge Ram Vans (some models): These are likely the closest example to a "vehicle" with a factory-installed 4BT. However, it wasn't a widespread option and often involved conversions or special orders. It wasn't a common factory offering like a V8.
* Various industrial and agricultural equipment: This is where the vast majority of 4BTs ended up. Think forklifts, tractors, generators, and other heavy machinery. These are not typically considered "vehicles" in the same sense as passenger cars or trucks.
It's important to understand that the prevalence of a 4BT 3.9L in a vehicle that wasn't originally designed for it usually points to a post-factory customization. The engine was exceptionally popular for conversions due to its durability and reliability.
