If you want economy, you should try a HOT air intake, as it will reduce air density and hence pumping losses at part throttle.
Secondly you'll never get fast enough to generate any useful amount of static air pressure via Ram Air Effect.
If you want to do something useful by making ducting though, it's very useful to make sure air entering the front of the motorhome actually goes THROUGH the
Power steering and brake cooler

Your engine will cool better, you may never hear your fan clutch kick in, and your transmission will certainly run cooler
