Portable Wind Turbine as a power supplement?
First post here, so I apologize if this is the wrong area. I'm doing research and planning out a custom RV (cargo van/step van/box truck conversion...undecided), and looking to be as green and self...

Using the engine alternator to charge the batteries on the road will definitely be more efficient overall than a wind turbine. The power for the wind turbine comes from the vehicle engine, but you have all the losses of going through the drivetrain combined with the extra parasitic drag of the turbine (something it's most likely not especially designed to minimize, since in most cases it doesn't matter that the wind is impeded more than necessary). Directly connecting your generator (i.e. alternator) to the engine is more efficient.
An extra foot or so of height can make a significant difference on overhead clearances in some areas of the country, such as New England. In other areas, low clearances are far less common, perhaps excepting tree branches. If the extra height puts you above the basic legal maximum of 13'6", you'll need special permits for every trip and be very much constrained on where you can fit.
Working to minimize power usage is just as valid as working to maximize power production.
