I agree, yet I see consistent claims about better trailer behavior where AEROTABS are installed. However much improvment in FE may be present is also open to driver skill (the hardest to quantify). The big truck industry pits drivers of the same company against one another to establish the range of possibility. And that difference is nearly 30%. 3% is hard to tease out.
IOW, I'd try the -tabs on a trailer (and may) and not consider it a waste if the trailer exhibited some better behavior in winds. Around $220 for a kit.
