Single piece overweight permit definition. Can I run this?

I’ll include a picture - to clarify.

Empty, the unit tractor and trailer is 80,000.

Potentially, when fully loaded with product - hydrogen - another 2,000lbs (?)

Though the trailer appears as 4 separate units, the entire unit is plumbed together as one, multiple cylinders in each pod - lines fixed , interconnected with shut offs and permanently affixed to trailer.

Can I permit to 80-85k if needed as a single piece non divisible?

 

Follow up question - I have an APU.

Does this allow 80,400? Or just 34,400 on drives?

 

That’s kinda what I thought. It apparently does have a weight when compressed.

My tiny mind brought up images of the Hindenburg . . .

 

His cat is pretty lightweight.

We shall swap cats for the voyage, weight should be ok then,

 

Are you answering the single piece or the APU question?

 

A confusing table also - axle/gross not directly answered?
