I just bought the snowcat and so far it seems to be a legit rack. I was thinking about buying a box for my car but then realized that I would have to spend some money on a cross bars and then more money on the actual box.
The snowcat only cost me $200 since I have factory installed sidebars and doesn't require cross bars to be installed. Win!
It only holds up to 4 boards. I think it can hold up to 6 ski as well.
