Other floor plans with a similar body style, feature mix, and price range, prioritizing other manufacturers and brands.
The 3731 is built around a rear bath and a half layout with a full side slide that opens the living space considerably, and the east/west bed orientation means you're not climbing over anyone in the middle of the night. Newmar's televator keeps the bedroom feeling open when you're not watching TV, and the booth dinette gives you a proper place to sit down for a meal rather than balancing a plate on your lap. Under the hood, the Freightliner M2 106 chassis with a Cummins 360L engine and Allison 6-speed transmission handles the 38-foot length with confidence, and Detroit Assurance safety systems. Active brake assist, pedestrian detection, intelligent high beams. Come standard. Owners consistently point to the full air-ride cab and hydraulic leveling jacks as things that make a real difference on extended trips, and the optional Lithionics lithium battery system with 640Ah and dual 3000W inverters makes serious off-grid capability possible.
