The new Ve-hicle came with roof racks, so I thought I was in sheet good
heaven. But upon closer inspection, these factory racks don't seem up to
much. I imagine they would scuff up in no time and they have no simple/fast
way to secure goods.

I was thinking I could make a 2x4 box (50x98) and dado a some plywood into
the bottom. I'd make a similar cover for the top, with wing nuts to hold it
down.

I think you can buy the glides that sit in the track, so I could use these
to hold the contraption on. I could also use the U bolt trick to hold it to
the existing frame.

Any thoughts?
