we have just had a semi air suspension system fitted which has improved the road handling I thought it would be good for when we use ferry.
We have had the tow ball bottom onto ramp when boarding so thought this would allow me to lift the rear to a height to clear the ramp.
After having it fitted I checked the distance it raised the rear when fully pumped up and found out it went up only 10mm which was very disappointing.
After speaking to my fitter he spoke to the manufacturer which is one of the main manufacturers they told him to alter the pump pressure from 3.5bar to 4 bar so this was done it made no difference has anyone had a similar problem if so what was the outcome.
