RV Select
Seffner, FL
This new 2026 Chinook Summit SS B+ at RV Select combines the maneuverability of a Class B with extra living space, featuring just 210 miles on the odometer. The rear-facing entry door creates a unique layout flow, while the front living arrangement maximizes your view through the cab windows.
What sets Chinook apart is their engineered steel substructure and secure cabinetry that owners consistently praise for staying rattle-free on the road. The convertible sofa extends your sleeping options beyond the rear bath configuration, and Chinook's Timberline heating system delivers exceptional cold-weather performance that outperforms industry standards.
The Summit is Four-Seasons Certified, featuring insulated construction and premium systems designed to help you travel comfortably in a wide range of climates throughout the year.
And the insulation works in both directions: the construction that helps retain warmth in cold conditions also helps reduce heat transfer from outside during hot weather, supporting a more comfortable interior across changing climates.
