Carriers (Bean Counters In Particular) will not buy into that reasoning. Why?
First, they consider the operational cost of a Sprinter to be lower due to a higher MPG average; therefore, in their way of thinking, it is an immediate financial benefit for the Sprinter O/O.
Second, they believe the Sprinter O/O will pick up a few extra loads over the conventional 48"H regular cargo van and that in itself is a financial benefit enough.
Third, only one out of 60-75 loads is ever three skids according to the shippers and Sprinter O/O's I have spoken with.
Finally, they don't have to pay an increased rate if they don't want to.
PS. I recently spent some time on the phone with a Sprinter O/O who was previously with a carrier who offered an incentive for Sprinter loads. Over the course of 12 months saw ran 6 loads that paid the incentive rate of $1.00/mile. 90% of her loads were not even at the carrier's advertised cargo van rate. They were a reduced "Major Account Rate" at 70 cents/mile. She switched to a carrier that paid her 75 cents/mile, increased FSC's, other deadhead paid miles and regular freight availibility. She told me just this evening that her income has almost doubled.
For her, she needs the nice sleeper, TV, desk, and microwave because she is a woman and does not like to stay in truck stops. Being a man, I am not subject to the vulgar cat calls and being hit on at truck stops, so the $47,000 price tag for a Sprinter of that type is too much for my budget. It works for her and I was glad to direct her in the correct path to increase her earnings.
