I've never had one of these on any of my trucks, because most of the stuff I've hauled — like motorcycles — didn't need any protection from the elements. But like Brett said on the HP, I see how they could come in handy for folks who have to keep things like tools secure. So do you use one? And what kind?

 

A lot of my friends do brutally long bike trips, and one of these could really help with a support vehicle.
