Don't sweat it.....yet. What part of this great nation do u live in? If u are north of TENN. East of Iowa, West of PA, South of Ontario.......... you'll do fine.
Location location location..you've heard it before i'm sure. You'll make enough (but what exactly is enough for you?) You'll end up doing probably 70% auto loads, and if you live in MI OH IN you might check into auto quick division. In speaking with single drivers in the south they all say its better running single "up north".
