also, rear visibility is not an issue. I usually leave the rear window blacked out to conceal all the gear I store in there, and the shelf in front of the cab backlight is usually packed with crates anyway. It does mean there's not much I can do about the big side mirrors - I need them.

looking down on the top:
here you can see the gentle radius on the back of the cab, and the scoop-like effect of the front of the cap. it just seems like it might pull some air into the low pressure zone under the truck.

Thanks! The top tells it all. You don't even have to cut the sheet, because you don't have the "metal bump/slat" thingies I was worried about. The cap shouldn't have to be metal, because you just lay the magnetic sheet to cover the gap and just rest on the cab. But, it may cost more.
Some sign shops also sell big magnetic sheets for putting ads on the doors of your car. They would have the biggest sheets, and probably no adhesive to deal with.
The sides don't lend themselves to magnetic sheeting as much because you don't get the benefit of gravity to "just lay" the sheet onto it. However, bed of the truck is metal, so you could use magnetic sheeting there.
You might try stuffing pipe insulation into the sides. However, you may not appreciate the aesthetics, and it may lead to moisture problems.
I have a small letter size piece at home. If I remember, I will put it on my wife's all-metal Civic and ask her to drive it around for the day.
