I have a 2012 Toyota Sienna with no gutters and no standard racks. I don't want to poke holes in the roof as I have a no permanent mods rule for my van. I've gotten down to the lowest amount of belongings that I want to keep but still need more storage for mostly clothing and maybe some low profile water tanks (eventually). So I am going to try this rack which is reasonably priced.

I'll let you know how it goes.
