Nice looking camper Mike !
That is a 2002, or new camper.
The 2001 Grandby Models had a "white" interior wall look.
The 2002, or new have the wood grain walls like yours.
Yes, the camper should be pre-wired for the fan.
Most people put an extra battery under the couch in a plastic battery box. They will take the exterior camper wire (grey wire usually on the front / driver's side corner - this has the white & black wire sticking out of it, or a plug), drill a small hole in the lower grey wood portion of the camper base, feed the exterior camper wire back inside the camper (under the front couch area) to the battery box you just installed, connect it to new camper battery, and then run a new similar wire back out another hole you can drill in the camper base (just next to the other one you made). Once the wire is outside you can add a truck to camper plug for it and finish up some camper wiring.
The White camper wire is POSITIVE +
The Black camper wire is NEGATIVE -
If you e-mail me directly at ... stan@fourwh.com I can e-mail you the older installation manual that should help guide you through it.
I'm not totally sure, but I'm 99% sure your camper should already have a power converter installed ??
We were installing them right about that time on all models.
Look under the kitchen sink for a small silver box with some wires sticking out of it. See sample picture attached.
Hope this helps get you started.

I just purchased a mint 2001 Grandby. I have a few questions that I was hoping someone could answer.
1. I have one standard roof vent aft. Is it pre-wired for a Fantastic Fan?
2. The unit does not have a house battery. If I install one, where is the best place to put it?
3. If I install a converter/charger, where is the best place to put it.
4. Are wiring diagrams available for these older units?
