Hi, this is a quick market interest survey as a part of my PhD research degree. We have succeeded to develop a flow modifier device name Aero-trek for caravans and horse trailers which can save you more than 10 % fuel and longer battery life for electric cars. Aero-trek provides a front covering to the caravan and saves it from chip damage. It also reduces side wind load on the caravan and improves the stability of the caravan in the strong side-wind.
Here is the link for further information about this product and concept design:
