Hello to all,
This is my first post or reply to any question.
I have a 2003 Fleetwood Revolution and last month I had a problem with airing up the coach. In the process of resolving the issue I learned a lot about the dump/air up system on the Freightliner chassis. While there may very well be a problem with the solenoid or dump/air valve, located behind and just below the frame mounted air tanks above the front axle, I suggest you disconnect the ride hight valves at the rear axle, move the frame attach rod to the up position and see if the coach lowers. Seems to me if the front of the coach drops than the dump/air valve is working. That is the only control for all of the aid bags.I hope this helps if not go to 1 800 FLT-HELP with your vIn#.
They are great and will walk you through the process,it is a 24-365 help line. jimt
