Land Rover Range Rover with Roof Rax Thule Force roof cargo box rental
Need more room for a road trip? Compare renting a bigger vehicle with renting a roof cargo box from Roof Rax in Southern California.
A packed trunk doesn't necessarily mean you need a bigger car.
If you're planning a family road trip, ski weekend, camping trip, or vacation and running out of room, you have two main options: rent a larger vehicle or add a roof cargo box to the car you already drive.
If your current vehicle comfortably fits everyone but doesn't have enough room for luggage or gear, renting a roof cargo box may be a more practical alternative to renting a larger vehicle.
Roof Rax is a Huntington Beach-based provider of premium Thule cargo box rentals, with a 5.0-star Google rating. We serve Orange County, Los Angeles, Inland Empire, and select surrounding Southern California areas. Compatible crossbars are available for many vehicles, professional installation is included, and our quoted prices include taxes. You can arrange delivery where available or choose self-pickup in Huntington Beach, California.
Renting a bigger car vs. renting a roof cargo box
Roof Rax pricing varies by trip length, vehicle compatibility, and delivery location. A separate refundable security deposit applies.
1. Do you need more passenger space or more cargo space?
Before comparing prices, identify the problem you're trying to solve.
A vehicle can have room for everyone and still lack the cargo capacity a road trip demands. This is especially common with children, a raised third row in an SUV, or bulky gear like camping equipment, snow gear, strollers, and multiple suitcases.
A larger vehicle may make sense if:
You need additional passenger seats.
Your current vehicle doesn't provide enough legroom or comfort for everyone.
A roof cargo box may make more sense if:
Everyone already fits comfortably in your current vehicle.
Your trunk fills up before all your luggage is packed.
You're bringing suitcases, camping gear, ski or snowboard equipment, or other bulky essentials.
You want to keep driving a vehicle you know.
The distinction matters because renting a larger vehicle can mean paying for seating and interior capacity you don't actually need.
2. When renting a bigger vehicle makes sense
A larger vehicle is often the better option when you need more than luggage storage. An SUV, minivan, or passenger van provides extra seating and interior space, which matters if you have more passengers than your current vehicle can carry. A minivan can be especially useful for families with car seats and strollers.
It's also the right call when items need to stay inside the vehicle, such as heavy items or unusually shaped gear.
Just consider the full cost and logistics first:
Costs go beyond the daily rate. Taxes, fees, optional insurance, fuel, and airport location charges can add up.
Pickup and return take time. You may need a ride to the rental location, transfer car seats and luggage, and return the vehicle afterward.
A bigger vehicle feels different. If you normally drive a sedan or compact SUV, a full-size SUV or van can be harder to park and maneuver.
These trade-offs are worthwhile when you genuinely need a different vehicle. If everyone already fits in your current vehicle, a cargo box is a simpler alternative to consider.
3. When renting a roof cargo box makes sense
A roof cargo box adds enclosed, lockable storage to the top of your vehicle. Instead of replacing your car, you add space for the trip.
It works well for:
Suitcases and duffel bags
Sleeping bags and blankets
Camping equipment
Beach gear
Ski and snowboard equipment
Bulky clothing and travel accessories
Moving suitable items to the roof frees up the cabin and trunk. That's especially helpful for families using the third row of an SUV, where the remaining cargo area may be too small for everyone's luggage.
Cargo boxes also work with many sedans, hatchbacks, and coupes. A smaller vehicle doesn't automatically mean you need to rent an SUV just because the trunk is full.
The biggest advantage is that you keep the vehicle you already own. There's no need to transfer your belongings into a rental or spend time getting used to a different car.
Why rent a cargo box instead of buying one?
If you only need extra storage for a few trips a year, renting may be more practical than buying. Premium cargo boxes and vehicle-specific crossbars can be a substantial upfront investment, and you'll need somewhere to store them when they're not in use.
With Roof Rax, you rent a premium, like-new Thule cargo box for the length of your trip, with compatible crossbars available for most vehicles and professional installation. You get the storage when you need it without having to store rooftop equipment afterward.

4. Compare the total cost
The best comparison uses the total cost of each option for the same trip dates.
If you rent a larger vehicle, add up:
The rental rate for the entire trip
Taxes and fees
Optional insurance or other coverage
Additional fuel costs
Transportation to and from the rental location
If you rent a cargo box from Roof Rax, add up:
The cargo box rental price for your trip length which already includes taxes
Crossbars, if your vehicle needs them
Delivery, if applicable
The separate refundable $99 security deposit
Your actual savings depend on your vehicle, trip length, and location. A larger vehicle may offer better value if you need more seats, while a cargo box may be more economical when your current vehicle already fits everyone.
For a fair comparison, get a quote for the larger rental vehicle that includes taxes and fees, then compare it with the full Roof Rax rental price for the same trip dates.
Before you pay to rent a different vehicle solely for luggage space, check whether a cargo box can solve the problem.
5. Which option is best for your type of trip?
Family road trips
If everyone fits in your vehicle but the trunk fills up with suitcases, strollers, and kids' gear, a roof cargo box adds storage without requiring a larger rental. If you need more seats or significantly more passenger room, go with the larger vehicle.

Ski trips to Big Bear, Mammoth Mountain, or Lake Tahoe
Winter trips mean bulky jackets, snow pants, boots, helmets, and luggage for multiple travelers. If you're driving up from Orange County, Los Angeles, or the Inland Empire, a cargo box can free up interior space for passengers and gear that needs to stay in the cabin.
Camping trips
Tents, sleeping bags, chairs, and other equipment can fill a trunk fast. A cargo box is perfect for lightweight, bulky camping gear and leaves the cabin for passengers and essentials. Roof Rax also offers YETI Tundra 45 hard coolers as an add-on to a cargo box rental.
Beach vacations
Folding chairs, towels, umbrellas, and accessories take up more space than expected. Moving these items into a roof box helps keep the trunk organized and leaves more room for passengers.
6. Does the box fit your vehicle?
Capacity varies by model, but fit is important. The box must be compatible with your vehicle, mount securely on the crossbars, stay within roof load limits, and ideally not interfere with your hatch opening. The combined weight of the box, crossbars, and cargo must stay within the vehicle manufacturer's limits.
Roof Rax helps match your vehicle with a compatible cargo box that provides useful storage while accounting for roof compatibility, hatch clearance, and applicable load limits.
Do you need crossbars? Yes, a cargo box mounts on crossbars that run side to side across the roof. Some vehicles have factory crossbars, others have roof rails that need crossbars added, and many sedans and hatchbacks have bare roofs that need a vehicle-specific rack system. A bare roof doesn't rule out a cargo box. Roof Rax provides compatible rental crossbars for many vehicles, so you don't have to buy a rack system for a single trip.

Yes, a roof cargo box can reduce fuel economy, particularly at highway speeds. The impact depends on your vehicle, driving speed, and the cargo box.
