I am a newbie also and maybe this is incorrect, but I believe what he is suggesting is that you have the Fleetwood ( FW ) coach number handy when you call. I have had to call Monaco several times for replacement parts and they always ask for the Monaco vehicle number. Mine is located on a label affixed to the outside of my coach right near the entrance door. There are several labels there, and one of them is from Monaco and it has stamped in it, the Monaco vehicle code. It identifies my exact coach so they can look the complete build sheet up on their computers and know exactly what was on my coach when it left the factory. I think that is what you need, and it should be located in a prominent location on your coach exterior.
Good luck with it.
