Best for couples who want a king-master-only floorplan with sleep count of 4 and no need for the extra slide or second toilet.
Pick the Newmar Ventana 4037 if…
Pick the Newmar Ventana 4037 if you carry 6 people, full-time or shoulder-season for long stretches, and want the documented 44,600 lb GVWR with 9,200 lb cargo, 800 Ah battery bank, 3 slides, bath-and-a-half plumbing, and four-season insulation. The Cummins L9 at 400 HP delivers more peak grade power, and at $548,825 MSRP it's $6,408 cheaper than the Discovery while bringing genuine working full-timer capability.
