Among respondents to Overdrive's power-only survey, 14% acknowledged similarities to traditional owner-op lease arrangements as a drawback of power-only operation. In systems where such similarities are the rule, too, the freight-rate negotiation skill that is often the strong suit of "traditional" spot market-focused independent owner-operators is wasted, another 34% suggested. Respondents choosing "Other" when asked to name the principal power-only drawback earmarked excess deadhead miles, limited freight access and "All of the above" among other negatives.
