I have a 2009 Monaco Camelot. A few years back I was inquiring about some parts with the Monaco tech folks, they use the last 6 digits of the unit serial number to identify the coach and look up it's history. The tech I was speaking with told me the first number of those last six indicates where the unit was built. In my case this number is 6 which indicates my unit was built in Coburg Oregon. He said he probably helped build my coach. I purchased this coach right after Monaco announced bankruptcy plans in April of 2009(got a great deal) and the dealer(DeMartini) told me that Monaco's higher end coaches are/were built in Oregon and the others in Indiana. I would believe if you have a serial number, a call to Monaco tech can tell which facility the unit was built in.
