The Fleetwood Frontier 39B runs on a Cummins 6.7L 360HP diesel pusher mounted to a Freightliner XCR chassis with V-Ride suspension, so highway stability is a genuine strong suit. Inside, the triple-slide layout opens up considerably, and Aqua-Hot 400D hydronic heating means both unlimited hot water and comfortable, even warmth throughout the coach. The kitchen comes ready for full-time cooking with a residential refrigerator, induction cooktop, and convection microwave, while Apex Custom Furniture and hand-laid luxury vinyl tile give the interior a more residential feel than you'd expect at this class. An optional Hide-A-Loft electric drop-down bed with a 32" TV, side-by-side washer and dryer, and Starlink satellite round out the Frontier 39B's list of upgrades worth considering.
