Lake George RV Park, in upstate NY, is certainly the nicest campground I have been in 12+ years. I go there 2 times a year (before pandemic).
Another nice campground is Normandy Farm (close to Boston), and Bayley's in Maine is not bad too.
I uploaded the "Monaco Monarch 2006 wiring diagram" to the archive, it will need to be approved, I hope there is not much difference between the 2005 and 2006
