Most Popular Roof Box for BMW X3

I can see why people consider the box a bit flimsy, especially when you do not have it secured to the car and nothing is inside. That’s normal. For this to weigh 34 lbs and yet to be wall sturdy and provide waterproof conditions that the bag cannot, it has to be lightweight. Once we attached it to the car at 4 points, it wasn’t going anywhere and was instantly sturdy. I wouldn’t roughhouse with the locks or opening it up and down with force however. Also, 14 cu for a sedan is plenty. Anything larger and you are looking to push the limits.

Bought this box to hold camping gear while on a cross country road trip. You can put quite a bit of stuff in it. Held securely to roof rack and kept contents dry. I liked that the key could not be removed if lid wasn’t completely closed. Minimal affect on gas milage.

Excellent car top carrier (not that I've had many to compare it to). Easy to install and remove, sturdy, and fits well on our Toyota Siena. Opening it is a little tricky, as sometimes the top sticks to the bottom a bit. Adds a lot of extra storage to our car, great for when we go camping. Great experience with etrailer.

Excellent roomy cargo box. My wife’s luggage even fit (see photo). Fit the top of my Forester like it was meant to be there and the hatch opens without obstruction. Great shipping by etrailer.com via Estes freight shipping (almost overkill on shipping).

This rooftop cargo carrier is exactly what I wanted. Well made and super easy to install. Thank you for the fast service.

The box is big (XL), shiny and sleek. Looks great on our 2021 Subaru Ascent. It weighs about 40lbs, so I was able to simply lift it up and onto the stock Subaru cross bars by myself with a bit of effort going towards balance. Then it was just a matter of attaching the clamps by hand tightening them. I don’t think it could get any easier. The locking mechanism is very assertive and secure. The box is big and can hold just about anything you’d need on a road trip. However, on a midsize SUV like the Ascent, it seems like the perfect size, not too small, not too big. It’s a good fit. Unfortunately, my small 2 car garage is too low to accommodate the vehicle with the box in place. Overall it’s a very refined and well thought out package.

This is a great car-top carrier. It is light and easy to install and move around. The opening and locking mechanisms also work well. I drove 5 hours with it in the rain and no moisture made it inside. eTrailer was also great when ordering. The freight company lost the first one and eTrailer simply sent me a replacement. Great company to work with.

Great product from a great company I bought this rooftop box for my daughter last year when she moved from Georgia to Oregon. It held well even in ran and snow. This is my second Thule rooftop box. I wish I had bought the first one from etrailer. They have great prices and great customer service.

my rooftop carrier! It was perfect for our golf clubs. etrailer was wonderful. Great communication and it arrived on expected date.

It was what I expected with a feature that I didn't expect. The quick mounting clamps make it very easy to attach.

I just ordered my 2nd cargo box from e- trailer. I really like this box and have ran it on multiple vehicles. Definitely recommend

This was a great experience from start to finish. etrailer: After placing the order, I called regarding shipping and quickly got the answer to my question. The box shipped by ground freight, and arrived almost a week before the original scheduled delivery date. The Rhino arrived perfect with protective wrap, and all the required parts. Rhino Rack: This thing is awesome. Unless you jump up into the $1000+ price point, your rooftop carrier options are limited. My two requirements were to fit my skis (181 & 183 cm) and to allow my tailgate to open fully. The Rhino delivered! Bonus that both baby strollers fit as well (Instep baby trailer and Vista Uppababy). Only a week in, but so far the Rhino box and MasterFit clamps seem solid. The ratchet/locking mechanism on the clamps is just ok, you don't have to twist too hard to over power the lock or feel like you are stripping something internally. The hinges are beefy, but don't take up a ton of storage space. It opens from both sides, and you can't remove the key unless it's locked, which is nice for those of us that don't enjoy picking up our stuff on the highway. Also, if you're like me and spent way too much time on mr-box.com, you'll be pleased to know that this thing doesn't look lame. It's pretty sleek, somewhat low profile, with a touch of Euro. It's not too wide, even on the narrow rails of the A4 Allroad there's extra bar space. I could probably squeeze an upright kayak rack, small ski pinchers, or for the ten of us in the world that own RoadShowers...the RoadShower 4 fits no problem. I definitely recommend a Rhino from etrailer.
