looking for a users manual

I bought my Carriage used but the previous owner gave me all the material that he got when he bought it new. All of it was from the manufacturers of the appliances and equipment. I contacted Carriage asking for schematics or wiring diagrams which I was willing to pay for and was told "we don't really have any" Yeah right, just take it to our dealer and he will help you out. I asked on this forum and no one else had been able to get their hands on one either. Very poor business practice from an otherwise good company.
