As a company driver I RAN on average, 4000 miles per week back in 05/06...
Company had terminals in Chicago and L.A. and i did 2 trips EVERY week and it wasnt ,,demanding'' so much as some people talk about it..
Now..., running 4000 miles per week in northwest or midwest with average lenght of haul at some 700 miles, i dont know about, but Cali to Cha town was a piece of cake..
Made good money back then, i was payed .36cpm..
