I live about 40 miles away from Nexus. I have toured the plant and met with both owners. As a "solo", I went with a Born Free coach.
Nexus builds a quality motorhome and the Ghost is impressive, but $$$. The step up to enter the shower was something I did not like.
A tour would be good for you. As you know, they are direct sale only with no dealers. They will tell you they have a "network" of service providers, but I think you will find out you will be on your own.
A good late model used unit with all the "bugs" worked out might be a good choice for you.
