Fleetwood Discovery 38W vs Newmar Ventana 3512
2027 Class A comparison · side-by-side specs, verdict, and who each is best for.
Quick verdict
The 2027 Fleetwood Discovery 38W is the newer model year - it's a 40.92-foot Class A diesel on Freightliner XCM Freedom Bridge with Cummins B6.7 360 HP, three slides, 33,600 lb GVWR, king bed, AGM batteries with 100W solar, 2,000-watt inverter, 105-gallon fresh tank, 8,000-watt generator, and three available floorplans (38K, 38N, 38W) for $509,266. The 2026 Ventana 3512 is 35.83 feet on Spartan or Freightliner with the more powerful Cummins L9 380 HP, four slides, 38,000 lb GVWR, full bath, king bed, 6,550 lb cargo, four-season insulation, 800 amp-hour batteries, and a 10,000-watt generator for $510,545.
The Discovery 38W's 2027 model year and the addition of a third 38K floorplan choice are the newer-build advantages. The Ventana 3512 still leads on chassis capacity (4,400 lb more GVWR), engine power (L9 380 HP vs B6.7 360 HP), slide count (four vs three), and four-season insulation. The Discovery's 5-foot length advantage is real for owners wanting more interior square footage.
Verdict: Discovery 38W for newer model year, three floorplan options, and longer wheelbase; Ventana 3512 for quad-slide layout, more powerful Cummins L9, and four-season build at near-identical price.
