Yes, the ABC Bus Co, Winter Garden Florida just helped me with my air bag problem and ride height control valve. My 08 Beaver Marquis. . The roadmaster chassis never was affiliated with Freightshaker co. The ride height should be around 9 1/2 inches top to bottom of bag supports.. There is not software to adjust the ride height as it is mechanically controlled from the ride height control valves... as for me I would also change the height control valves as they fail without warning. There are three of them rear left side and right side on the drive axle and the front axle. Good luck The service writer is ALEX at ABC company. Oh they have pits to drive the coach over to make it easier to work on. 800-222-2871
