Each year, my family rents a house at the beach. Traveling to the beach with two teenage/adult children in tow means bringing a LOT of STUFF! Several years ago, we purchased a rooftop carrier to help with packing. The first was an old, hard sided carrier that was heavy and hard to use. Two years ago, we purchased the Axius Rooftop Cargo Carrier. This unit is softsided and molds to whatever you pack into it! Eventhough it is waterproof canvas, we try to pack things that wouldn't be affected by the weather if they were to get wet. Last year we loaded it with our boogie boards, fishing gear and some of the household items that we bring such as toilet paper, paper towels and napkins. In the two years that we have used it, nothing inside has ever gotten wet even when we have driven through some minor rain showers.
Using the rooftop carrier frees up room inside of our SUV for more "valuable" objects and gives the kids some room to stretch out in the back seat for our 12-13 hour drive. The carrier has helped eliminate arguements as to what to bring or what to purchase when we get there. I can pack just about anything I want and not have to worry about running to the store as soon as we pull into the house!
If you have a long drive ahead of you or plan to pack a good deal of luggage for upcoming travels, consider purchasing the Axius Rooftop Cargo Carrier!
