My friend, who is a girl (thanks Sheldon!), claims Forest River makes the best RVs out there in terms of quality and insulation. Like me she's an engineer and has been researching RVs for her retirement. Unlike me, she's still working and doesn't have an RV and has never owned one. I'm on my 4th Class B.
She doesn't like my Roadtrek, but then if an RV doesn't have a full basement, 4 bedrooms, 3 baths, ceiling fans, hot tub and swimming pool it's just not worth the trouble.
