That poor poor poor idi..I'm impressed it still pulls its self.

 

I think you need a CDL is the primary braking system in pneumatic if I recall correctly. That and your GVWR of the vehicle.

 

Not federally you don't.

 

Well, its not required for every state by the looks of it, but the great state of CA on the other hand..

A commercial motor vehicle is a motor vehicle or combination of vehicles designed or used for either the transportation of persons for compensation or property and:

Has a gross vehicle weight rating (GVWR) of 26,001 pounds or more.
Tows any vehicle with a GVWR of 10,001 pounds or more.
Tows more than one vehicle or a trailer bus.
Has three or more axles (excludes three axle vehicles weighing 6,000 pounds or less gross).
Is any vehicle (bus, farm labor vehicle, general public paratransit vehicle, etc.) designed, used, or maintained to carry more than 10 passengers including the driver, for hire or profit, or is used by any nonprofit organization or group.
Transports hazardous materials requiring placarding.*
Transports hazardous wastes (Health and Safety Code §§25115 and 25117).*

 

I unfortunately live in Commiefornia, and thats right, any vehicle with more than 2 axles you need a class B to drive.

 

I've seen one other truck like that... it was a fire station truck. '85 or '86, I believe. The rear axle is a floater... just there for supporting the added weight of what's on the back of the truck.
