Pick the Newmar Northern Star 3709 if…
Pick the Newmar Northern Star 3709 if you're full-time RVing or planning extended trips and want the higher 38,000 lb GVWR for legitimate four-season living with heavy cargo, the bath-and-a-half for couples sharing the coach, and three slides for genuine residential floor area. The 8,000-watt diesel generator, 400 Ah battery bank, and four-season package handle dry camping and winter use the Forza 34T can't match. The price premium reflects the Newmar build quality and capability headroom.
Pick the Winnebago Forza 34T if…
Pick the Winnebago Forza 34T if you want a Class A diesel pusher under $365,000, shorter for easier maneuvering, and you're stepping up from a gas coach into the diesel ride and torque. The Cummins ISB 6.7L at 340 HP still pulls strong, and the two slides plus residential fridge and theater seating cover most couples' needs. You'll trade cargo capacity, slide count, and bath-and-a-half for over $51,000 in savings.
