The Cascadia I got uses DEF...hopefully not too much damage ..then again I have no choice in the matter if i'm going to get some rest can't sleep in the heat!
I'm not sure you understood what I said. Revenue/mile is not pay/mile, as you said. The business of collecting revenue is controlling cost....hense greater return on expenditures ( in trucking #1 FUEL ) The guys/gals that do it for a living will correct me if I'm wrong, but I do know business. You'll get it, I'm sure.
Don't worry everybody idle, I did when I had the cascadia.
Basically you mean it's no longer how many miles you run but how much you can get while driving less miles. Less miles means less diesel wastes while making the most money you can
