As stated before most people who don't care for Tiffin have never owned one. It is usually a story about somebody else who they knew----. We too know somebody who bought a 15 Entegra and had to go straight to the factory as soon as they picked it up. We are not going to get into that. Both are great coaches. I can not speak for Newmar as we have never owned one and only an owner can speak for their experiences. I have heard that Newmar will fix their problems. As far as Tiffin: we are on our second and love it. Tiffin has always gone out of their way to make our experiences on service great. If we buy another coach it will be a Tiffin.
