Here is a link to front suspension used on Alpine Coaches. Our 2002 unit has AS 120 series suspension. The manual includes parts, service and trouble shooting.
There is a good section on adjusting ride height.
I found this while looking to see if suspension limit straps were necessary to lift front end off the ground with the front leveling jacks. Manual does not go there, I can understand why with all the liabilty concerns now.
Has anyone purchased Koni shocks and where did you find the best prices.
