no more space issue
This box is awesome for any extended trip if you want 4-5 people to feel comfortable in your car. I got it for my prius and it is not too long for that type of car. You may want to convert the antenna into a sharkfin one to avoid the box bending it.
For ski trips: It can easily fit 2-3 pairs of skis along with a couple of snowboards and boots. It is long enough to fit any type of skis as well. You can then use the trunk for all your other stuff.
For surf trips: It can fit 2-3 shortboards. Don't count on having longboard though! Haha. And you can keep all the wet stuff in the box too.
The installation takes 2 minutes really and doesn't require more than one person to do it.
