Newmar Bay Star Sport 3225 vs Winnebago Adventurer 34W
2026 Class A comparison · side-by-side specs, verdict, and who each is best for.
Quick verdict
Both of these 2026 Class A gas coaches sit on the same Ford F-53 chassis with the 7.3L V8 and identical 22,000 lb GVWR, so the real differences show up in length, electrical, and amenity loadout. The Newmar Bay Star Sport 3225 measures 32.92 ft with two slides, a king bed, and a 5,500-watt onboard generator, but ships with 30-amp shore power and just 1,950 lb of cargo capacity against a 20,050 lb dry weight.
The Winnebago Adventurer 34W runs 2.6 ft longer at 35.5 ft, drops to 96 in wide instead of 101.5, and upgrades to 50-amp shore service, residential refrigerator, theater seating, washer/dryer prep, and solar/generator prep rather than a unit installed. Holding tanks are similar (75/57/48 vs 75/60/40 gal), but the Winnebago carries 18 gal of LP versus 25 on the Newmar.
Directionally, the Newmar Bay Star Sport 3225 is the shorter, generator-included Class A for owners who want to roll off the lot fully equipped, while the Winnebago Adventurer 34W is the longer wide-body Class A with stronger residential furnishings and 50-amp infrastructure.

Pick the Newmar Bay Star Sport 3225 if…
Pick the Newmar Bay Star Sport 3225 if you want a Class A under 33 ft that fits older state-park sites and standard residential driveways, and you value an already-installed 5,500-watt generator and the larger 25-gal LP tank for boondocking weekends. The 101.5 in wide body opens up shoulder room without committing to a 35-plus-foot footprint, and the king bed plus full bath keep the layout simple for couples who occasionally host. The 30-amp service is the trade-off, so plan for one rooftop AC running at a time on shore power.
Pick the Winnebago Adventurer 34W if…
Pick the Winnebago Adventurer 34W if you camp at full-hookup 50-amp resorts and want a residential refrigerator, theater seating, and washer/dryer prep wired in from the factory. The extra 2.6 ft of length opens up a roomier salon, and the solar and generator prep let you spec the off-grid kit you actually want rather than paying for one you don't. This is the better Class A gas coach for buyers prioritizing residential interior amenities and 50-amp infrastructure over a turnkey generator install.
Frequently asked
Which one tows behind better at GVWR?
Both ride a Ford F-53 chassis rated to 22,000 lb GVWR with the 7.3L V8. The Bay Star Sport 3225 has a published 1,950 lb cargo allowance with 20,050 lb dry weight, while Winnebago does not publish a dry weight for the Adventurer 34W.
Can either run two air conditioners on shore power?
The Adventurer 34W with 50-amp service can support dual AC units on shore power simultaneously. The Bay Star Sport 3225 is 30-amp shore service, so dual-AC operation requires running the 5,500-watt onboard generator.
How do interior dimensions compare?
The Bay Star Sport 3225 is 101.5 in wide with 80 in interior height. The Adventurer 34W is 96 in wide; interior height is not published, but expect roughly comparable headroom in this Ford F-53 segment.
