Though I've watched the video before I did not remember the mention of synthetic lube.
Looked closely at the leaking cover and did find cracks as mentioned......ordered both covers.
I hope the parts support for these chassis continues since they stopped making them what 10 or more years ago. Thought briefly maybe we should have looked harder for an F53 chassis for future parts support?
It seemed the most wise advise here about finding a coach is to look at the condition and not get to hung up on chassis manufacturer.....which is what we did. It is a great coach and I did really want the Allison so all in all we're happy
