What kind of generator is behind this sleeper thanks

Ok, I had to change the contrast to see what you were referring to. Yup, there is a large component behind the sleeper fairing, two fans on top and access door on bottom.

Thanks

 

Is it cng tanks?
Looks that way to me.

 

The mystery deepens . . .

 

lol, ya, and Ill be derned if I can find a pic anywhere of the backside of one of those transporter tractors.

 

since it's a truck for shows at races, etc, it could be a rental generator, like movie productions use.

All of the big race teams in the NHRA, Nascar, etc carry their own power supply for their use in their pits.
