Road Trip Roof Cargo Carrier Guide

This is where roof cargo carriers come in. They offer a fantastic solution for expanding your vehicle's storage capacity and bringing all the essential gear you need for your next escapade. But with two main options available - roof boxes and roof bags - choosing the right one can be a puzzle. Don't worry, we're here to help! This comprehensive guide will delve into the world of roof boxes and roof bags, exploring their advantages, disadvantages, and the key factors to consider when making your decision.

Roof Boxes: A Secure and Spacious Choice



What is a Roof Box?



Imagine a sleek, aerodynamic pod mounted on the roof of your car. That's essentially a roof box! Typically constructed from a durable and weatherproof hard shell material like ABS plastic or fiberglass, roof boxes offer a rigid, secure storage compartment for your belongings. They come in a variety of sizes, ranging from compact options suitable for weekend getaways to expansive cargo holds that can swallow camping equipment, luggage, and more for extended adventures.

Advantages of Roof Boxes



  • Security: Peace of mind is priceless, especially when you're entrusting your valuable gear to a rooftop carrier. Roof boxes excel in this aspect. Most come equipped with robust locking mechanisms that deter theft and keep your belongings safe during your travels.
  • Organization: Unlike tossing everything into a giant duffel bag, roof boxes often feature internal compartments or dividers. This allows for better organization of your cargo, preventing items from shifting around during transit and making it easier to find what you need when you reach your destination.
  • Aerodynamics: Let's face it, nobody wants to spend extra money on gas because of a bulky cargo carrier strapped to their roof. The good news is that many roof boxes are aerodynamically designed to minimize wind resistance. This translates to better fuel efficiency compared to a roof bag and a quieter ride on the highway.
  • Capacity: If you're the type of adventurer who packs for every possible scenario, then a roof box might be your perfect match. They offer a significant amount of storage space, allowing you to bring along all the gear you need for your trip, whether it's camping equipment, sporting gear, or extra luggage for a family vacation.
  • Protection: Mother Nature can be unpredictable. One minute you're basking in sunshine, the next you're facing a downpour. A roof box shields your cargo from the elements, keeping your belongings safe from rain, snow, dust, and even the sun's harmful UV rays.

Disadvantages of Roof Boxes



While roof boxes offer a plethora of advantages, it's important to consider some potential drawbacks before making your purchase.

  • Cost: Compared to roof bags, roof boxes tend to be a more expensive investment. Prices can vary depending on the size, brand, and features, but you can expect to spend a few hundred dollars or more on a quality roof box.
  • Storage: Let's face it, not everyone has a spacious garage to store a bulky roof box when it's not in use. Their rigid design can make them challenging to store in tight spaces. However, some manufacturers offer roof boxes with detachable mounting systems, allowing you to remove the box itself for easier storage.
  • Height Restrictions: Adding a roof box to your vehicle increases its overall height. This might seem insignificant, but it's crucial to consider potential clearance issues. Be sure to factor in the height of your car with the roof box installed before heading into low-clearance areas like parking garages or drive-thrus.
  • Fuel Economy: While aerodynamically designed, a roof box does add some wind resistance to your vehicle. This can result in a slight decrease in fuel efficiency compared to driving without a cargo carrier. However, the impact is usually minimal, especially when compared to the significant decrease you might experience with a roof bag.

Here's a helpful table summarizing the key advantages and disadvantages of roof boxes:
