Crusty, I've run a few UPS and FedEx loads, and yeah they do suck. Run like all get out show up, run like all get out to deliver. I hate'em, but when your under forced dispatch what can you do? Turn down too much freight, and you'll find yourself out of a job.
And getting a job when you're experienced is not as easy these days. Larger carriers want students to burn out, and the good smaller carriers don't hire as often because they're drivers stick around.
Hope everything works out for you, and welcome back to the wonderful world of trucking...such as it is.
