Bill, you would probably find that the "builders" manual is not worth much. For the most part they are simply generic manuals, that cover the entire line(s) from the builder. There is nothing on the refer, heater, water-heater, A/C, axles, etc. Those are all covered by the manufacturers manuals of the respective item.
You might be able to get PDFs from the various component makers.
Personally I would get the RV Repair and Maintenance Manual by Bob Livingston.

When someone tells you to buy the same rig they own, listen, they might be right. When they tell you to buy a different rig then they own, really pay attention, they probably know something you don't.
