Stability Product Evaluation...
Over the last 13 years I've owned two 35 foot Class A diesel rigs, both with Freightliner chassis. During those years, often noticed an instability on either freeways or two lane roads. Rocking, rolli...

When a large truck passes an RV a high velocity mass of air pushes against the roughly 10' by L' flat surface of the MH. It defies the laws of fluid dynamics that the small fins at the very rear of the RV could do anything substantive to change that force.
The fins would have some effect on the turbulence of the air flow that comes down the side of the MH when in motion. That could be measured in a wind tunnel, but I've never heard of these wind deflectors (lots of different types) being tested in such a facility.
However, if the "warm fuzzies" one gets from investing in such devices makes driving the MH more enjoyable, it could be worth the cost.
