Gurney Flap on a Pick-Up Truck

This thread is a "how to" on what NOT to do if you want to save gas.

This modification will cost you gas, although it will add some tracking stability on the highway which I like very much.

The crazy version:

How it is today:

The flip down hinge I installed two years ago has since rusted to a set angle. Should anyone do this, use stainless steel piano hinge from a boat supply store.

The shorter Gurney flap will cost you about 1 mpg on the highway, but I like the added stability at highway speeds so it's staying.

In Michigan we get black ice, and after a night of that pick-up trucks can be found in the trenches off the highway and in the grassy/snowy divided highway area. For this reason I'm keeping my Gurney Flap, it's a safety feature at this point. And like most safety features it costs a little in gas mileage.
