Seriously when you buy your rocket box think of what your going to do with it when you don't have it ontop of your car.....
yes this took 2 of us 3 hours to install. BUT now I don't need anyones assistance to remove the box off of my rack ever again. The hassle in installing this bad boy saved me countless hours of removing and placing this box on top of my suv with someone else's assistance. I would highly consider buying this. But please don't think that this rack can store your gear inside of your box while it is attached to the rafters of your garage. Personally I would not enjoy having my gear falling on top of me or the roof of my suv incase it collapsed. Amazing device, and wicked sturdy. a major score for my clutter free garage.
