* Specific trim level: Different trim levels might have slightly different suspension setups or ground clearance.
* Modifications: Aftermarket modifications like lift kits significantly alter the angle of departure.
* Loading: A heavily loaded Suburban will have a lower angle of departure than an unloaded one.
To find an approximate angle of departure, you'd need to consult a 2005 Chevrolet Suburban owner's manual or a reputable automotive specification website that provides detailed dimensions for that specific year and model. Even then, it will likely be an *approximate* figure.
