That's heavy man

Heavy Haul trailers are amazing pieces of equipment.

Some states (3 that I know of) require the ground load on the pusher to be within 10% of the drives when permitted. There is a valve/system that automatically adjusts the lift axle air pressure to satisfy this requirement utilizing an air ride suspension. It is available in the aftermarket, if your OEM does not install in the factory. Reach out if you'd like to know more.
