Medium checked luggage can fit in larger rental vehicles like SUVs or minivans, providing ample room for several bags when traveling with family or groups. However, it may be snug in smaller cars, so it is essential to check the trunk dimensions beforehand.
Large checked luggage requires more trunk space and is best suited for larger rental vehicles. If you choose a compact or economy car, you may need to limit the number of large bags or consider alternative packing solutions.
Duffle bags can be easily squished into tight spaces, making them a great option for fitting into smaller rental car trunks, especially when you need to maximize space. Their flexible design allows for better accommodation in different vehicle types compared to rigid suitcase designs.
Backpacks are particularly convenient for road trips, as they can be stowed under seats or in any available space. Their compact nature allows for easy maneuvering in tight trunk spaces, making them a popular choice for travelers.
