We just got a 06 wagon, and wonder if any high-capacity boxes long enough for skiis fit without modification on the stock rack. Ones we tried block tailgate from opening fully. Thanks in advance for any help.

I've seen LOTS of those with the Thule Rocketbox mounted. It seems to ride far enough forward to avoid tailgate problems.

Same idea, but I think Rocketbox is a trademark of Yakima, and the smaller one will work.

 

We have a Thule Frontier 1100 cubic in. that works great -- holds 5-6 pairs of skis. They also produce one called the Ascent 1100 & 1700 that should also work. They're all 91.5 in. long.

 

When installing them, try adjusting the cross bars in order order to avoid interference with the tailgate.
