Hard to say, it seems they like to run newbie drivers a bit, before giving them decent home time.
That said, I stay out 2 weeks at a time, and sometimes longer if I have appointments I need to make on Thursday or Friday.
The new trucks are Cumming 13liter, and Cummins won't unlock them, so 67 is it. They still like to push the mpg limit on us, but if you're close or running heavy loads, they won't complain too much. Of course, the tractors are Internationals, and they just aren't all that. For what we're expected to do, we don't get much more than the minimum to do it; and the AC units in the sleepers don't work well at all.
Biggest problem, besides FMs with bonuses that are more important than you are, is they're cutting costs in alot of areas (tarps, tractors, techs, straps, etc) that they shouldn't be doing so. Plus driver turnover is horrendous.
I've been here 2 years now, and overall had a good run, mainly because I've had two very good FMs that made sure I get good runs, and get home when I want to. My only concern is the corner-cutting that's affecting everything else we do. Otherwise, the cpm is decent (.40 to start as a rookie), the benefits are excellent, if a bit pricey; and they won't question you if you have a problem that needs fixing, a tire blows, or if the weather is so bad you feel unsafe driving in it.
