Most books for things like this have been replaced by YouTube videos. You can find most anything there, just make sure that the person posting the video appears to know what they are talking about. And I know you want something specific to your motorhome, but most RV stuff can be fairly generic. For example you're looking for chassis maintenance info on your specific motorhome make and model, but many many other makes of motorhome will be on the exact same chassis as your motorhome. I have a National Tropical, but it sits on a Freightliner chassis with a caterpillar engine so when I look for maintenance stuff for the chassis, I'm searching Freightliner and Caterpillar, not National Motorhomes.
