Wind Deflector for Caravans

[Jeff.C Junior Member Find all posts View Profile Close Jeff.C]

Has anyone fitted a "Aeroplus wind deflector" to the roof of their Prado ? they allege that you can save around 13% on fuel costs.I have only seen one and the owner reckons that he saves on fuel and also the rig wants to go faster downhill ( less drag resistance) and also less buffeting when passing trucks,
Would be interested to know if they work,

20 years ago I used a suitably braced bit of ply on the roof racks to direct air up over the top of the pop top van I had at time behind my 60 series. I don't know if it affected fuel consumption but there were never any bugs on the front of the van.
