Pick the Winnebago Forza 34T if…
Pick the Winnebago Forza 34T if you want the Cummins ISB diesel chassis for sustained highway grades, better fuel economy on long trips, and the Freightliner XCS platform that holds its value longer than gas Class A's. The 84 gal fresh tank, 8 kW generator, 2,000 W inverter, and 48 gal black tank are working full-time numbers. At $361,072 MSRP, the $79,532 premium over the Bay Star buys the diesel pusher experience in a 35.5 ft package.
