i dnt know how they are but here is my experience with them, i use to drive back in the day (2002) out of huntersville terminal, 1600-2000 miles per week, and that 2000 was if i was lucky and got home saturday morning!!! i remember leaving huntersville monday afternoon and delivering tuesday morning in PA, sitting ALL day waiting for a load and then when i did get one is was 153 miles to deliver the next afternoon
they run east coast only!! if you get one of the old green macks, they are slow and horrible on fuel, i fueled up 3x on one of my good 1800 mile weeks
