They tell me the DH miles the LH miles and the amount and the amount they are paying me (the money paid doesn't always come over with the load offer, but that has been discussed before) if i check anything , its a quick check to see what it is paying per mile, but after that , nope i don't check it for accuracy...i put it in the gps and go...Now i will say this, i have 3 gps's in my van...chances are really good that they all will have a different mileage...they will be close but chances are not the same....
I have never called Load 1 dispatch to ask about mileage differences, its always close and not an issue...
The detour situation, i had a run that went down I-40 about 4-5 months after the rock slide that had closed it, they miles dispatch sent routed be over to Johnson City, and they told me up front..
