I am not aware of anything like this, especially not anything that focuses on coaches so much like ours.
The session coordinator spoke to me about the need to get Cat expertise at the sessions, both because of the Beavers that attend but also because of some of the REV lines added to the mix. The problem is that having abandoned the on road engine market, Cat has little interest in supporting the Maintenance Session or anything else related to RVs. I suggested that he get in contact with the local Cat dealer, who might be more amenable because of the service opportunity.
