What kind of generator is behind this sleeper thanks

Here - let me clear this up. It's a typo.

A Jenny Rater is a top secret machine developed by Lucas that scans a 3- mile radius around the truck, identifies any person named Jenny, and then rates them on a 1-10 scale, displaying the results and location of said Jenny to a heads up display in front of the driver.

You're welcome.

 

I am under the oppression the OP is just a nascar rig fan.

 

I’m out.

 

Maybe he's referring to the reefer unit on the trailer

 

Not as pretty but this is used to power the minuteman Payload Transporter III trailers.

 

Awww come on - can’t give up that easy

 

I think it was made by the manufacturers of the Turbo 3000D, but Lucas bought the patent, so it’s trustworthy.

 

I thought that was obvious.

 

Zoom in, look behind the sleeper. Im assuming thats what he is asking about.
