So I don't have a new Coachmen, I have an older one - pre-acquisiton by Forrest River.
I agree that first and foremost, you need to rethink towing that thing with the QX56. My two cents is that while it may pull it, you won't enjoy it and it'll really be rough on the SUV.
I'm in a similar quandary considering a purchase of a newer Class C. I think when it comes to quality, most of the manufacturers in that price range are going to be very similar. They all build them as quickly as they can. One cuts corners as much as the other. They all source their appliances, pumps, components from the same suppliers.
In short, IMHO, it's a **** shoot. Stop analysis paralysis and pick one. :) Read up on how to do an inspection before you take delivery. Read up on how folks have fixed common issues. Read up on what kind of experiences folks have had with warranty work.
That's where my head's at with our pending purchase.
