Well Al, I've owned only a bounder and a Winnie, I have loved them both. Neither is perfect but both had/have great features and accessories. I have heard great things about both Tiffin and Newmar and in my opinion it boils down to floor plan first and price second. If price is of no great concern, it boils down to floor plan and even though not mentioned earlier, the bright work and upholstery.
I think I would look at Newmar first, just because I have read far fewer negative things or problems with Newmar. That doesn't mean the other two are not great.
