I get that you're not pleased that you're paying the tow bill, Jim. I get that it's like salt in your fresh wound.
Our experience is that we've had one animal collision, and two breakdowns while under a load, both while we were leased to FedEx. In the cow strike, the tow bill was added to our collision repairs. In one of the breakdowns, we were 1.7 miles from the delivery. I never even thought to ask FedEx for the tow. Our premise is that it was our promise - we promised to get the freight from point A to point B at X price. We did exactly as we promised. On the other breakdown, the light going to the switch inside the box for the box lights rubbed inside the box panel and grounded out the top section of box lights. It was a sealed load, non-government, but hazardous, non-secure (not any type of defense). I called and asked permission to break the seal. Nope. I asked if we could call the state police to witness us breaking the seal, and sign off on re-seal. Nope. Got towed 155 miles to the delivery, and had to find tow driver with hazmat endorsement. Soon as we got there, unloaded, and repaired wire. Took all of one minute. I won't elaborate on what the chemical was, but doubt sincerely that this was some type of "mission critical" or true expedite load. It's used in making a food product. Since FedEx never asked to be reimbursed, I never offered. The tow driver could not wrap his head around towing for some bad lights. I also thought it was a little dumb. I let them pay.
All that said, we promised to haul the load. They trusted us to do it, and we're going to do everything in our power to make it happen.
I know. Not what you wanted to hear.
