I could use some help locating diagrams for wiring ect.. to the coach of this model. Just purchased this old guy in fantastic condition but I have no information on the wiring, plumbing ect of the living quarters itself. If anyone knows where, or someone has one and can share diagrams ill be indebted. Tried the company that manufactured it. They no longer have those records. They only have ones dating to 98. Any help would be appreciated.
