This is just a guess but possibly some spilled diesel fuel while he was refueling or leftover residue on the ground from previous spills. Also the hot exhaust may have caused a flash fire(wonder if the truck was running while being refueled).
Like I said, this is all just a guess as the heat damage is (not surprisingly) focused on the tractor(what’s left of it).
Just had another thought. If his brakes caught on fire It’s possible that fire may have spread to certain areas in the engine compartment, especially if it was his steer brakes that lit up first.The fire may have spread to other components in the engine compartment, like the power steering, or the fuel rail.

I doubt his steers will be involved.

There is a persistant old iron rule that may still be correct and it goes like this.

Steer axle brakes do not have springs on them for parking purposes and feature a pretty low air application force compared to the other cylinders.

Well here’s another old rule: Where there’s smoke,there’s fire!

Could be there was enough of a barometric change inside the trailer. Paper burned up all the oxygen, fire below the trailer cooked it like an oven, then some point of the trailer had a failure resulting in a compression rupture.
