In development for nearly 16 months, Newmar's London Aire - a nameplate last seen eight years ago - was brought back for 2015, though the former company flagship is now positioned as an "entry-level" coach for Newmar's 600-hp diesel-pusher lineup. "What we wanted to do for 2015 was develop a product at the entry level of the 600-hp price-point - a more value-priced, affordable 600-hp luxury motorhome," said John Sammut, Newmar's vice president of sales and marketing.
