The first fifty eCargo vans arrived at the Callahan Freight depot in Phoenix in October. Tyler Briggs delivered them personally. He drove the first one through the gates himself, in a brand-new Desert Sterling shirt, grinning from ear to ear.

He'd already sold eleven more vans to two other delivery companies. Carol Benson said he was the best young salesperson she'd hired in twenty years.

“He treats every customer like they're about to buy a fleet,” she told me. “Even if they're buying a car mat.”

My drivers lined up to try the new vans. Big, quiet, cool inside. The seat that adjusted for a bad back.

One of my oldest drivers, a man named Earl who'd been with me since I had three vans, sat in the driver's seat and adjusted it. He sat there for a long time without saying anything. “Well?” I said.

“Joe,” he said, “my back's been killing me for fifteen years. This is the first time I've sat in a van and it didn't hurt.”

Tyler, standing beside me, looked like he might cry.

“My dad would've loved this,” he said quietly.

“Bring him down,” I said. “He can test-drive one.”

The next Saturday, he did.
