The cylinders are a mystery. Seeing only a grayscale picture, the

said that's where service trucks carry it. Its color corroborates this.
Why would a pipeline welder carry refrigerant?

The truck has welding hose on a reel beside the spare tire, but I see no
cylinders marked for acetylene or industrial oxygen. Could he get
anyone to put anything but medical oxygen in a tank marked for medical
oxygen? Carrying highly compressed gas in loose cylinders looks very
dangerous.

How have you concluded that the tanks do not contain welding gases? In
the US there's no standard color code for gas cylinders. The standup
tank behind the passenger door looks like a fuel gas cylinder (MAPP if
I had to guess), and there's no reason the green tanks lying down in
the bed can't be welding oxy.

When you hear hoofbeats, think horses, not zebras.
