Chinook Summit Motor Home Class B+ - Diesel

The Chinook RV Summit Class B+ diesel motorhomes are uniquely handcrafted with quality and style! These models will take you away from traffic, off the beaten path, to the creek, and through the mountains. Parallel parking on a city street will be a breeze too with their nimbleness and maneuverability!


"Unlike any motorhome in its class", "unique among its peers", and "elegant interior" are just a few of the raves rightfully given to these motorhomes. A Mercedes-Benz Sprinter chassis holds these units together and a 6 cylinder diesel engine powers them. With a gold level certification from Truma and all-season functionality, these units set a new standard for Class B+ motorhomes. Each unit has been rigorously tested in a cold chamber at -15 degrees Celsius overnight to prove they can withstand the cold winter months and even the hot summer days!


You won't have to worry about what time of year to go traveling in a Chinook RV Summit Class B+ diesel motorhome!

Chinook had been one of the top names in motorhomes since its debut as Mair & Son, Inc. back in 1938.  However, it was not until the early 1950s that mass produced motorhomes started hitting the road, only proving that Chinook RV has consistently been an innovative leader in the motorhome industry, which stayed true throughout the years.  With the incorporation of fiberglass, Chinook was able to be one of the first companies to create a sleek and aerodynamic design; making Chinook one of the most sought after brands.


Due to Chinook’s early success, they began to further their use of fiberglass throughout the overall construction process.  In 1971, the first one-piece all fiberglass shell had been successfully developed and this  sleek body style revolutionized the entire RV industry and had customers trading in their boxy, gas guzzlers for the beautiful aerodynamic design.


Chinook’s unparalleled innovation set a tone in the market as the best brand in the nation for decades.  However, no one stays at the top forever. The Great Recession in America hit hard and Chinook RV was forced to end production in 2005. By the following year, the doors were officially closed.  


In a phone conversation in February 2011 with Chinook’s then owner Gary Lukehart, he stated the original manufacturing jigs and equipment were being kept in storage on his ranch in Yakima, “until a time when the economy may improve and someone may decide to make an investment to bring Chinook back.”  Luckily, his patience paid off when he received a call from a man in Las Vegas. The online community of Chinook owners felt the ground shake as news broke that the rebirth of the brand was in progress. Phil Rizzio, the owner of several large U.S. dealerships, purchased most everything from Lukehart and took over the process of resurrecting the brand in 2013.  After three years of hard work and dedication, the Chinook RV legacy was reborn.
