Great question, we are in same position, albeit early in the research phase. A lot of variables in finding the right DP, starting with price range. But for your question, I'd like to buy our next coach from a company that not only wants me to buy my first coach from them, but
also the next and the next after that. After 28,000 miles and experiences owning the Axis I am inclined to buy our next motorhome from either Newmar or Tiffin. The Tiffin Allegro RED or Newmar Ventana is in the lead at the moment. I'd like to stress that I'm not looking for or expecting perfection.
I'm a member in both Newmar and Tiffin forums, I probably over research
The Comfort Drive from Newmar seems like a huge hit from those who have experienced it. Overall satisfaction from both Tiffin and Newmar DP owners seems high, though bug fixes and issues requiring attention are also common place.
