Thanks Ken. That's very interesting as all tonneau manufactures claim some kind of increased MPG (around 10%) and I'm just gullible enough to believe them. Although, it would be nice to be able to put my groceries in the bed instead of the cab on a rainy day. Maybe I'll just save myself $300 and put it towards gas.
