I have a Yakima gutter mount rack and the hi-rise kit but when I tried to mount it, the angled towers hit the side of the near-vertical Westy top.  But today I saw that exact arrangement on another Westy on the freeway, although I could not get close enough to see how it was mounted.  Anyone have a clue?  yes I know I could get the fake bolt-on gutters and drill holes in my pristine top but I would rather not do that.  Please reply off list.  

Thanks
