Could somebody please tell me the most I could possibly make per mile with a 20 foot box capable of carrying 22,000 or 23,000 lbs (Tandoms)- would I be able to get paid "D" freight from Panther if I were to work for them? Class8 Kenworth W900L or T800L- 13.2 front- super 40 rears 120 inch sleeper-18 foot box with gate. No house payments- No Wife-No car payments-Just me and the truck. I just like big trucks and big horse power (cummins 525) and most of all being comfortable. So the box length has to go. Not interested in Semi.
