I bought a 2018 Nexus Phantom about a year ago. My wife and I had wanted one for a long time, and our family got tired of tent camping. We took it for an 8 week, 10,000 mile trip last summer, towing a Jeep, and it was amazing.
I don't have other RV experience to compare it with, but as a newbie I was comfortable driving it within a week.
I got it for way below list price, and then had a bunch of stuff done to it, and it still came in under your budget.
Part of the trip last summer was a stop at the Nexus plant in Elkhorn for a factory tour, and all I can say is I love my Phantom but envy the Ghosts.
