Just a thought; have you considered dry bulk tankers? I do dry bulk cement and love it. It's like the best of both worlds (local/OTR). Very seldom wait anywhere for anything. No humping freight; just pump it off (takes about an hour to unload more or less depending on product). Takes about 15 minutes to load. Other than that (and pre/post trip), nearly all of your time is logged on Line 3. When I run a 14 hour day, I'm watching my Line 3 hours a lot closer than Line 4. In the end, I average 2300-2500 miles per week running two states
in a daycab and home every night. It's not uncommon to have an assigned truck AND trailer (we even get to take ours home). Options are out there for local, regional, and OTR. Pay may be flat per load based on distance, mileage based, or percentage of gross. And I haven't seen too many dry bulk venues that require the hassles of hazmat (doesn't even require a tank endorsement).
I originally thought this would be a great stepping stone to lead into a future running liquid tankers, which I wanted but wasn't possible with limited experience. Now, I think I'm perfectly happy where I am
