Purchased this for my 2011 RAV4. This is the perfect size for this vehicle. When place as far back on the roof (right in front of radio antenna), the cargo box stops right before the curvature of the roof starts going downward at the front of the vehicle. I believe this minimized air getting caught under the cargo box and creating drag. While driving, I haven't noticed anything different. Fuel efficiency is about the same. I am sure this would be different if there was some cross-wind, but nothing of that happening in NYC during this review. The weight of the box is very light. Easy enough to be picked up by myself. Installation was quite easy, 15-20 minutes to install with no additonal hardware required. Since the RAV4 has a hatchback door, it was easy enough to stand on the rear bumper to access the cargo box. The construction is OK. The shell is made of semi-hard plastic. There is definitely flex to it. This product is not made of hard plastic, but I am sure something like that would have cost twice, maybe three time more. For the cost and size of this cargo box, it is a good buy. I was lucky enough that this box fits perfectly for the RAV4. I wish we could upload photos here and I would show how aesthetically pleasing it looks on my RAV4.
X-Cargo XL - great price, disappointed with durability, wind noise and wind turbulence. I bought this product due to the price and reviews. However, I am disappointed. Driving while it is empty is NOT an option. It bangs against the roof at speeds over 60mph (I had to do this because I purchased out of town due to availability locally). Shakes a lot at almost any speed. Even when full, noticeable wind noise in cabin of vehicle, not too bad but I can definitely tell it's up there due to the wind noise and drag. Lid is very cheaply made, flexes a lot when opening. Haven't taken an actual trip yet over 100 miles but planning on one soon. I do not have high hopes I'll be satisfied with this unit and will likely return if a longer trip, loaded, does not yield a change in my review.
The carrier appearance is excellent. Price paid gets 5-stars. Unfortunately, the material used is/are not the best affecting workmanship. The topper warps easily. In my case the Florida sun and heat took a toll on the topper. It can be easily open from the sides (my case). Thus, if you have large bulk items no need to worry, small items can be easily lost. i would have gave it 5-starts but the warping and lack of sturdiness drop it to a 3-start.
Love this Car Top Carrier Unit. This is the second one I purchase after losing the first one to heavy damage in Storm Sandy. The first was crushed after my garage collapsed. This product allows you to have extra room in your vehicle on long distance trips. I already used it on a long drive from New Jersey to Florida and it lived up to its reputation. Durable through rain or shine. Highly recommended.
Easy to put up. Light weight. Top is a bit flimsy when open.
