Here's your first DIY project! Since the kind of manual you are probably asking for never existed, you get to start your own. You can download a chassis manual from the auto manufacturer, ie. Ford E-350 van. Then, as nosticks recommended, download manuals for the components, furnace, A/C, water heater. Either print them, store them on the cloud or save them on a flash drive.
Next, access Ed Felker's excellent manual assembled for Vegas/Axis. Much of what's there will apply to your coach, too. Happy trails!
