I bought an '05 Georgetown XL Used and the most important manuals are the ones for the appliances, jacks, slides, etc.
The Forest River manual was not of much use. It actually showed a picture of a Class C MH and all information was pretty generic.
You do need the Ford Chassis manual. I assume Ford V10. It has some helpful info. Like, when I thought my cruise was failing, the Ford manual confirmed the the cruise will drop out under heavy strain and rely on the operator to control the throttle. Saved me a service charge.
If you have a local dealer, he might be able to help. Maybe let you sit in one of his units and read the manual.
Life is a journey, not a destination.
