Thule Force XT XL Rooftop Cargo Box - 18 cu ft - Black AeroSkin - TH6358B

Average Customer Rating:  4.8 out of 5 stars   (217 Customer Reviews)

82-3/4 x 33-3/4 x 17-1/4. This aerodynamic, low-profile cargo box holds outdoor equipment and large luggage for up to 5 people. Quick-Grip clamps let you quickly mount the box to your roof rack, and the locking lid opens from both sides.

by:

This cargo box fits well on our Toyota Sienna. It is lightweight but awkward for one-person handling. I would say that the hinge mechanism is novel and well designed. Due to the length and flexibility of the box itself, opening and closing can feel floppy before the box is secured to the roof.
We have only used this twice in the past year, on two 1,000 mile trips. One included a sustained, driving rainstorm. All of our luggage stayed dry. There is minimal wind noise. Due to much higher weight (passengers, luggage) and greater tire inflation, I can't quantify the fuel economy impact. Our Sienna averaged 25 mpg while driving 75 mph on the interstate.




by:

We just came back from a 2000+ mile trip from Maryland to the Gulf Shores. This cargo box worked flawlessly. The extra 18 cu ft of storage contained 3 carryon bags, 1 large suitcase, fishing gear, a small tent and an acoustic guitar. Had initially ordered the Yakima Grand Tour but it was backordered till next year. etrailer was able to provide other options and after comparing 6 boxes, this box was selected for its larger capacity, dimensions, price and aesthetics (it looks like an escape pod for some spacecraft). The length is longer than the Yakima but the frontal area (which is more important for range) is slightly lower and narrower. Mounting it on the factory crossbars was very easy. It takes only minutes to install or remove. The initial installation took the longest as I wanted to make sure it was centered before I marked the crossbars to make the next install easier. The box does flex a little on bumpy roads as we can see the front from our windshield but there were no issues driving in the low 80 mph range.




by:

The locking mechanism is VERY difficult to use, not sure if it is a defect with my box or a common problem. Also, you have to make sure it is aligned perfectly at three different points when closing, or the lock won't even engage. I have had to ask several strangers to assist me in locking/unlocking and loading up after a long ski day. Not user-friendly for one person.


Comments
I reached out to the manufacturer who will be in contact with you.
-- Etrailer Expert Jenny N - 03/17/2022


by:

Remarkably easy to install - in less than five minutes. My wife and I easily lifted it in place, applied the attachments and were ready to go. Conveniently opens from either side. Able to adjust front to back and side to side to get to the optimal position on the roof rack. Even positioned as far to the rear as possible, the back gate of our Honda Odyssey opens with about two inches of clearance. Looking forward to our first loaded road test.


Comments
One year in and still loving it. Extra storage for a cross-country move, tents and sleeping bags, ski equipment, you name it-it fits. Easily handled skis, poles, boots and helmets for a family of six. No visible wear and tear and works as well as the first time. Definitely a good investment.
Mark - 07/23/2022


by:

Do not buy this unless you want to spend 5mins+ every time you shut the lid. The locking mechanism is frustratingly horrible! On a positive note the available cargo space is amazing, it sits solid on the roof of my 4runner and it is impressively quiet on the highway. Unfortunately the difficulty in getting it to latch shut negates all of the positives.




by:

With every single penny of it. The best. Very satisfied after owning it for a year.




by:

The Rooftop Carrier has been everything we expected.




by:

It was exactly as I had envisioned. I can’t wait to take it out on a trip to see if it performs as expected.




by:

Outstanding service and overall great experience! Had to cancel one due to back order, switched it to the Force XT with no problems. Great experience!




by:

I ordered from etrailer because of price, price guarantee and product detail information was outstanding.




by:

A little more flimsy than I had hoped. I know, Thule is trying to save weight, okay. The clasp devices that holds the cargo box in place is worth the price. They are so easy to adjust and are very secure. Also, the ability to open the box from either side of the SUV is also worth the purchase price. Everything inside stayed dry in heavy rain. I really like the finish on the box. Good Product!




by:

Made many road trips with this guy and it’s never leaked and never had any problems. Occasionally it’s hard to shut but that is more my fault for overloading it a bit.




by:

THe product is great. It got here in time for our vacation


Comments
It has been great. Allowed us to get all the extra stuff out of the car until we need it. Easy to attach and remove.
Nancy - 08/17/2022


by:

This Thule box has been great. It may not be the cheapest one out there but it's easy to install and all the mechanical functions are high quality. We have used this a number of times over the past year and I can store enough luggage in here for 5 people over the course of at least a week. Great for skis too.




by:

Extremely satisfied with this product, exceeded my expectations.




by:

Very happy! Exactly as shown. Great purchase and fantastic price. Never disappointed when I order from etrailer.




by:

great response and quick shipping excel lent




by:

Not many complaints. Great quality. Does what it is suppose to do.




by:

easy install and very easy to open and shut. Love it. Only thing I did notice is one of the plugs was missing from the cap.




by:

Thw box looks awesome and was super easy to install. It came on time and in perfect shape! Thanks




by:

Easy to secure atop oem bars of honda pilot 2019 and looks great. Easy to liad unload from either sude. So far, very happy.




by:

Delivered on time and everything was gr eat!




by:

Very happy with the product. It was just delivered, so we have not used it yet, but we are excited about all of the additional storage space we will have next time we take our Volvo on a roadtrip. It is very attractive and has a ton of storage space.




by:

Unit has performed flawlessly atop our 2018 Nissan Pathfinder. So much so that at 80+mph there is no aerodynamic disturbance to be aware of. Method of attachment makes Thule easily on and off for an outing at a moment’’s whim. Capacity held 7-days worth of winter clothing and skies for two adults along with toys for two children. I’ll buy no other brand as Thule is tops in all categories.




by:

The product is perfect for our needs. Adam at etrailer did a great job in supporting our order.

The best part of all is that you would sill be able to open the hatch with the cargo box installed. In regards to position, this will...

    For your 2019 Cadillac Escalade that has factory crossbars the Thule roof cargo boxes like the part # TH6358B are a confirmed fit and a great solution for roof top storage. Roof boxes are give you a great way to carry extra cargo outside of the vehicle and the nicer boxes like this one are very easy to install. Some boxes use difficult to line up U-bolts but this uses a quick grip style of mount that easily grabs the roof rack crossbars. For more info check out the review video I attached...

    I believe you are asking about how to find out if you will be able to open the hatch of your 2019 Subaru Outback Touring with the Thule Force XT XL Rooftop Cargo Box # TH6358B installed. Determining this is very simple; all you need to do is measure from the middle of the front crossbar to the seam between the hatch and the roof.

  • How Much Clearance Does the Thule Force XT XL Require To Open Rear Hatch
    The Thule Force XT XL # TH6358B requires that your Rhino Rack RS Roof Rack must be positioned on the vehicle's roof so that there is a minimum of 23-5/8" between the front and rear cross bar (center on center) and a maximum of 35-1/2" between them. The Force XT XL also requires 51-1/8" minimum between the center of the front crossbar to the spot on the roof where the rear hatch meets; as long as you've got that much space you'll be able to open your rear hatch unobstructed.

  • How to Position Roof Cargo Box on Roof of Vehicle
    You have the exact right idea for how to position the Thule Force XT XL Cargo Box part # TH6358B on the roof of your vehicle. Having it as far back as possible that would still allow the rear gate to open would be your most ideal setup. This would give you the least amount of wind noise and still give you access to rear hatch.

  • Thule Force XT XL Compatibility With A 2008 Subaru Outback
    The Thule Force XT # TH6358B will fit on your roof, but you need to check some measurements to make sure. Make sure you can spread your crossbars out at least 23-5/8th inches to no more than 35-1/2 inches. That's the spread required for the thule box. If you have factory crossbars the clamps will be compatible! So you should be good to go!

  • Will 2013 Toyota RAV4 Antenna Interfere with the Thule Force XT Cargo Box
    Whether or not the antenna on the 2013 Toyota RAV4 will interfere with a cargo box or not depends on several factors. First, if the antenna does not stick up higher than the top of the crossbars then it will not interfere. If the box is not long enough to reach the antenna it will not interfere. If the antenna is flexible then it also should not be an issue. Based on the length of the Force XT cargo box, # TH6358B, at 82-3/4 inches and its ability to be more forward or backward on the...
