You won't find a better coach. Monaco made a quality product and the Camelot is the first level that goes to a side radiator in the Monaco lineup.
There was one issue with a couple of models.......I'm not sure what year. They had a really flat roof in the engine compartment and retained heat when you stopped. Monaco did a repair that cut a long slot (about 6" x 6') above the engine doors and installed some 12 volt radiator fans (like those used in new cars) to pull the heat out. This was no big deal, but something to think about if you discover a heat issue.
There is also a generic issue with Monaco coaches and many others. The roofline clear coat does not hold up well. Most Monacos of that era, the clear coat has gone bad on usually the front cap and one side.
Make you get on a ladder and inspect all four sides of the roof. The repair to repaint and fix the issue, is about $3500.00. This may be a bargaining chip you can use.
Again, these are minor issues, the Camelot is a great coach and the above two issues are not something that would scare me away.
