your on the 70 hour rule... a tip, to help with the split sleeper, I've found that using a stopwatch and/or digital timer is helpful.
When you start your 14 hours, start your stopwatch/timer...
when you stop to log sleeper berth time - stop your stopwatch/timer.
When you come out of sleeper berth logging, start the stopwatch/timer again.
This way you'll always know without 2nd guessing, exactly how much time you have left (legally).
Digital timers work the best, set it to count down 14 hours, that way when you get up and take hold of the wheel again, you'll know when you start the timer count down up again how much time you got left.
As a solo, it really helps, esp. when the QC watchin' so closely. You won't have to talk with the log dept./safety dept. so often.
