First of all, you need to think about what you want to put in the box.
Outdoor enthusiasts commonly use Withcar roof boxes to hold tents, sleeping bags, sleeping pads, backpacks, camp furniture, strollers, skis, ski poles and ski boots. But these systems are also great for other things, such as gardening tools, beach items and children’s toys.
As you consider what you’ll be cramming into a box, focus your research on what length, width and height your gear requires. And, as you do so, keep these two points in mind:
- things that are bulky and lightweight fit well in car roof boxes
- things that take up a lot of space but don’t weigh a ton are good items to put on top of rooftop boxes.
So, things like tents, sleeping bags, sleeping pads, pillows, camp chairs, etc. are perfect to be answered in the box.
Longer items require a longer car roof box: if you plan to store long items, such as skis and snowboards, shorter and more compact boxes may not be right for you. Many car roof boxes fit most downhill skis and snowboards well, but if you have exceptionally long skis (like a pair of 210 cm cross-country skis), then you need to pay close attention to the length of the box. Compare the size of your skis or other long items to the inside dimensions of the boxes to make sure they fit properly.
Roof boxes for cars and heavy objects
Heavy things are best stored inside your vehicle – most cargo boxes are designed with a maximum weight capacity listed on the owner’s manual.
To avoid reaching the maximum weight, it’s best to store very heavy items inside your vehicle, such as a full cooler, water jugs, and dry food bins.
