Re: 2000 Avion Savannah Fleetwood 5th wheel
An Avion is a very well made trailer, but they are no longer in production. In fact 2000 is just about the last of them.
It is true that a lot of things are generic, but a lot of things are not. We had a Avion as a trade in last year. Super, super nice unit, leather furniture, hard wood floors, seamless countertops and all that, but we never did figure out what some of the wall switches did.
Fleetwood might be willing to help you with manuals if they don't come with it, but be sure whoever you are buying from explains all to you.
