Aero shell
 

As requested here's a pic of my aero shell...I worked on this thing for hours, then decided that I probably couldn't use it, since I wouldn't be able to reach in, and grab my tools from the back of the bed...If I made it have an opening lid, or opening sides I would have to add so much weight to the truck that the gain in weight would counter any aero design economy...tough choice...decided on another design, will follow up with new pics when finished.

sorry tried again...filesize still too large to upload...any answers on reducing size..etc..?

I use paint.net to resize my photos. Its free. Paint.NET - Free Software for Digital Photo Editing
Resize is in the "Image" pull down menu.

You can also host large images on a free image hosting site like Image hosting, free photo sharing & video sharing at Photobucket or ImageShack® - Image Hosting and just post the thumbnail or link here.

Also, regarding the weight vs. aero consideration, the aerodynamic benefit will be greater than the weight penalty.

added weight
 

A 1,200 pound weight addition to my CRX cost me only 2-mpg.
