Rear wheels on Heavy trucks sometimes get raised up off the ground completely. Its meant to be more efficient or something. Would love to see what results can be achieved in beamng's T-series )
do you mean drop axles? On triaxle's the middle axle is usually a drop to avoid tire wear..would be nice..But the devs mostlyy focus on cars and light vehicles
If the T-Series ever gets remastered like the other Gavrils have (it seems they plan on at least touching up everything) then a triaxle is a good possibility.
