I goofed and ordered a "good deal" on used gutter mounts for a Thule
roof rack from someone on Amazon.  Turns out I only got 2, not 4.
Not terribly helpful and the seller is not admitting to a mistake.
So, in moving on, I still need 2 more gutter mounts for a roof rack
to accommodate 2 crossbars.  I went to REI today (Thule on sale!) and
they only have a 4-pack available.  Thule only shows a 4-pack on
their website.  I will call Thule on Monday and find out if they will
package and sell just 2 gutter mounts.

The preamble above is to inform the bigger question: I know I have
seen Westies with three crossbars and I want to know how those are
being used.  If the solution to my problem is just to buy the 4-pack,
I want to know how this may benefit me down the road.  How would I
make use of three crossbars in the future?

Thanks, all!
