APU that runs on kerosene?

Looks like the sign reads “ for apu heater only” kerosene burns cleaner than diesel.

 

I would guess that it's probably for an espar or wabasto heater and those units like kerosene.
Truck looks like a k@b unit and they probably fill the tank at the terminal.

 

The sign I see reads, “Absolutely no washer fluid, oil or any other kind of fluid in this compartment.”

 

Look at the fuel tank

 

Look on the tank. Yellow sticker

 

You guys are just trying to trick me into looking at the photo again, but I seen the sign on the sleeper, above side box door.

 

Aww man you’ve figured out our evil plan... @FLtoOKBound lets start plan 273

 

Me: What are we doing today 062?

O62: same thing as always. Trying to take over the world.

 

That’s a big tank just for the apu.
