MIOD : WELCOME to iRV2.com
You have come to the right place for answers and information about RVing. CONGRATS on ordering a new coach, especially one of the finest made! AND on the W-24, the biggest and best gas chassis available. You won't regret it
I have to admire someone who is already planning his first oil&filter change before his coach even arrives! Since it is on the W-24, I am not comfortable with telling you which filters to buy (although I don't think they are different), I would rather suggest you spend some quality time with your new owners manual you will receive with the coach. Newmar does an excellent job of putting all your manuals in a quality case, and you will receive a rather thick owners manual from WCC as well. There is also a CHASSIS GUIDE available for downloading at the WCC website.
May I also suggest you drop down and visit us in the WCMC section below, where you will find all sorts of Workhorse related discussions.
Again, Welcome and congratulations on your choices-you're doing great! ED
