However, unless I have company, I don't even bother with the racks/box. I use an "interior" box I made that fits behind the driver's seat through the narrower opening of the split rear seat. It is adjustable for ski length, and is also waterproof so I don't get melted snow into the vehicle.
Do you have pics of that setup? I'm thinking of fabbing something like that up for our Jeep. It's usually only my wife and I going to the mountain, so we put the skis in the back with the seats down.
