the counter where it said in the contract that the miles were unlimited. He underlined where it said exactly that, but he also said I have to return the truck to the same location and I only had it reserved for the minimum 5 days.
OK.
I drove from CA to TX and pulled a trailer back home with it. 5 days, ~4500 miles.
When I turned it in, it was the same guy. I could tell he was shocked at the miles, but also clearly remembered our counter conversation. Best $400 I ever spent.
