Routing lanyards over and around the wishbones of the IFS is problematic in my estimation (and apparently in Freightliner's too, since they didn't provide them lke they so on solid axles).
When I bought the coach (used) in late 2006, I took it to the FCC factory a few months later to establish a new service baseline. They drained some water from the tanks and changed out the air dryer. Also had some air leaks, which they fixed. Since then I have changed the air dryer faithfully and it has been staying dry.
I don't run the engine a lot in Florida - I head north!
