I had an 04 Carriage 37ft, not Cameo, and really liked it. The fit-and-finish were excellent.
The only problem I and my neighbor had, his was an 04 Carriage also, was the Grey Water Tank. If you let it get full it leaked at the seam where the top of the tank is joined to the main holding area of the tank. It happened to both of us I and do not know if it was manufacturing defect or the pressure of over-filling caused the rupture. I took the easy way out and never let the tank get full.
I did not experience any problem with the Black Tank, but I was very careful not to let it get full.
I thoroughly enjoyed the Carriage and do not hesitate to recommend it.
