Hadley system 450LXi

[dentmac]

As for used, I don't think any used would be available as they are custom for the 450. Hadley will want proof of certified side to side weights and front weights before they would consider a change. Changing to the larger tires/wheels is good for the tire consideration. I doubt that Hadley would ever allow the change -liability -why would they? Whats in it for them?
They made the change at BB request in 2008 before BB removed other steel from the front end.
BB won on this one-- did it without telling owners.
As for de activating the solenoid joining the right and left airbags-- No purpose and may be dangerous. The air pressures in each front bag is controlled only by the need to hold the average level. If the flow rate from the Hadley manifold to each bag is uneven or if one side has a small leak then the other side will increase pressure. The system remains happy because the "Average level" is satisfied. The discrepancy is masked by the rear twisting the coach to maintain basic level.
Outcome is one side overloaded, front end un-level in drive mode- which screws up alignment and tire wear in a IFS .
