has anyone done a roof raise where they streamlined the 'forehead' and made a gradual slope or curve to the raise? - maybe 6' long? - I'm thinking a bit of effort to make things more streamlined during the raise will pay off on fuel savings eventually - suggestions are welcome
- I've thought of a sleeper cap used on tractor trailers might be good, until I priced them - thought of using the fibre glass front of a 5th wheel trailer, but they would need too many alterations to make them practical
