Anyone find a non-rusting roof basket? Or a decent aluminum one?

 

I bought a Surco (spelling?) basket a number of years back used that is aluminum that hasn't rusted. I put it one every year when hunting season and take it off when done. Doesn't really help with mileage when on but does allow me to empty the back of the Blazer when I have to put a critter in the back.

 

This is the first thing that came up but found the racks later. Same name under surcoinc.com.

Thanks...
