How to Choose the Right Cargo Box: Thule vs. Yakima Roof Box Comparison

Let’s Talk About Rooftop Cargo boxes for your Car

Hey there, fellow traveler! Rack Attack team here! — your go-to spot for all things vehicle storage, travel, and turning your car into the ultimate road trip machine. Whether you’re heading to see the in-laws or planning a weekend in the mountains, packing your car efficiently can be the difference between stress-free cruising and chaos on four wheels.

Let’s face it — if your car’s starting to feel more like a clown car packed with bags, kids, bikes, and the dog, it’s time to consider a rooftop cargo box. Today, we’re diving into why you need one, how to choose the right size, and how two of the top brands — Thule and Yakima — stack up against each other.

Why Invest in a Rooftop Cargo Box?

Let’s start with the basics. A cargo box isn’t just an accessory — it’s a game changer.

1. Free up interior space: No more elbows in the ribs, cranky kids, or the dog looking at you like he needs more legroom.
2. Stay dry and organized: When the skies open up, you’ll be grateful your duffel bag isn’t swimming in rainwater.
3. Better packing strategy: You can separate luggage, gear, and essentials to avoid the dreaded "Where’s the toothbrush?" game at every pit stop.

In short: more space, more comfort, less mess. What's not to love?

How to Choose the Right Cargo Box Size

Before you go big, there’s one crucial factor: hatch clearance.

Hatch clearance is the distance from the front crossbar on your roof rack to your fully open rear hatch. If your box hits the hatch when it’s open, it’s too big for your vehicle. Simple as that.

Want to avoid the guesswork? Visit a local Rack Attack, and our team can measure it for you. But if you're shopping online, make sure to check hatch clearance specs on any box you're eyeing.
