+1 on Crabby Mike. You'll pick up a raft of valuable generalized info that will convert well from one large DP chassis to another. But all information will be presented based on Freightliner construction. Other chassis may have appliances located in different places, or have systems designed with slightly different features.
Having said that, you'll find CF valuable. I've attended twice, and learned much on both occasions. Worth the trip.
