Hi 00Roadking
We have had our Monaco since September '09 and have been full-timing in it ever since. It has had it's share of "issues" since, but we are hoping that those who warned us that we would have them for the first 20K, or so, and that after that, they would settle down, were right.
As you know, there is no warranty from Monaco on your coach. I understand that Cummins and Allison have manufacturer's warranty still in effect, but we have had no warrantiable problems with either, so who knows. What I wanted to add about the new Monaco Corp (read Navistar) is that, even though they guaranty nothing on coaches they didn't build, their factory customer service line has been extremely helpful with me in resolving problems that have come up. As an example, we broke a tile in the bathroom, and the folks at Monaco CS researched the vendor, found the tile and arranged to have it shipped to us so I could replace it. I had to pay for the tile, of course, but without Monaco's help, it might have been impossible to locate.
Hope this helps
