* Rear: This is the most general and neutral term.
* Back: Similar to "rear" but less formal.
* Tailgate: This refers specifically to the hinged door that opens to access the cargo area.
* Cargo area: This refers to the space inside the vehicle behind the rear seats.
* Trunk: While SUVs don't typically have a trunk like a sedan, some people still use this term to refer to the cargo area.
So, the best term to use depends on the context. For example, you might say "I loaded the groceries in the rear of the SUV" or "The tailgate was open."
