The hours of service, log book, is against you. If you get 10 hours work today chances are it delivers at 6AM. You empty and go in the sleeper at 8AM. Then you must sleep for at least 8, before you can head to the next load. Well, everyone is going home and you are available, with no load till the next day, if you are lucky. A B unit, no log book, yet, can work for a solo. But the carrier may have rules that amount to the same thing. Best advice I can give is don't buy a truck till you have some experance.
