mjdunk sorry you're not going to find what you're hoping for. Most manufacturers of that ear just assembled a folder full of the various items (A/C, heater, fridge) and considered it good enough. With the model numbers you can probably find the vast majority of them, though at 11 years of age some will be harder to find. As for switches for lights etc, you can post pics here and some might be able to give you some advice. Sadly when Fleetwood went belly up they totally kicked the towable owners to the curb, there is no support from the new Fleetwood. Feel free to ask away about specifies though, many folks here can help out in some way, many Toy Haulers are very similar.
