Here's my class A towing episode:
It was the Mass. Turnpike on a early Friday afternoon in November. I was driving from Providence, RI to Lake Placid, NY on college visits with son #2. Blew a serpentine belt near Springfield, MA.
Tow driver knew a Workhorse chassis place, they had the belt, and we were back on the road by 5pm. Mass. Turnpike also send a separate truck to drive the family to the repair location.
I explained to my son that repairs DO NOT normally happen that fast and we could have been stuck in MA until Monday if the part was not in stock.
