We have a 2003 Toyota Tundra, rated 15 city, 18 hwy. Long trip planned with scooters in the truck bed.

1) If I were to delete the pipe rack and add a canopy, what kind of mpg change should I expect? Does anyone have an educated guess?

Obviously, a tonneau or boat tail would be better, but wouldn't leave room for the scooters.

I know that mythbusters tested tailgate up, down, mesh tailgate, tonneau, etc.

2) Does anyone know where I can find the data from their tests?

3) Did they also test a canopy?

Thanks,
Miles
