The comment by Gritz Carlton above in post #5 is exactly why I wrote and compiled the manual for my 2015 Vagas 24.1 that I've shared with over 1400 people here on the forum. (The manual is available here

The manual in addition to explaining how systems work contains troubleshooting suggestions; how to sections; locations of fuses, switches, relays, valves etc.; modification suggestions; setup/tear down/equipping/winterizing checklists. I updated the manual as new model years were introduced and systems changes were incorporated in newer models (for example: replacing the tanked water heater with propane on demand hot water system).
The sticky for my manual contained in the Motorhome Tech Topic section of this forum was viewed 7482 times. Another sticky that has the list of all the construction drawings I compiled for my Vegas and shared with others on this forum has been viewed 6792 times. As I said earlier I have either forwarded by email or have had my manual downloaded more than 1400 times. All this is a clear indicator that there is a huge demand to fill the RV information void.
As I've said hundreds of times: owning an RV is an adventure in self-discovery.
