There are manuals in the FAQ Forum for just about everything as well.
Wiring diagrams are a bit more difficult because the manufacturer uses "shop drawings" to wire the campers. Wire colors can vary greatly based on what they have on hand in that gauge at the time the camper is built (it seems).
A few generic wiring diagrams are available in the FAQ that have been discovered by members.
The baggage door keys are most likely CH-751 keys and are literally EVERYwhere. Find a friend with a camper and borrow one to copy. MOst every camper in the world uses the same key.
The door keys can be made for you at a dealership provided you have the VIN and the owner's card (I have heard).
