I have a 4'x8' trailer I pull on the highway sometimes. When I have the sideboards up, the thing feels like a parachute attached to the car. It catches much less wind if filled to the top, and I can barely tell the trailer is attached when the sideboards are off. The rolling resistance just isn't much of a factor compared to aero.
