Even if it doesn't kick in after delivery to the layover, and even if deadhead is 50 percent, that's still 30 cents a mile, which is a decent rate of pay for a Sprinter driver who doesn't own the Sprinter. There are new drivers for large carriers, like Werner, that start off at 28 cents a mile all miles. And they have big-truck crap to deal with. And co-drivers that smell really bad. At 1500 miles a week at 30 cents a mile, that's still a $450 weekly paycheck, or about $90 a day on a 5 day week. Not great, but not bad. But then again you're not gonna have 50 percent deadhead, either. It'll be more like 15 or 20 percent.
Of course, there is the sitting. Some weeks you'll be doing good to crank out 800 miles. Other weeks you'll do 2500 or more. But the 800 mile weeks happen more often than the 2500 mile weeks. But over the long term, 1200-1500 miles a week is what you can expect as an average. Plan accordingly.
