Quick verdict
Both Class A gas motorhomes ride the Ford F-53 chassis with the same 7.3L V8 engine, but layout philosophy and pricing diverge sharply. The Newmar Bay Star Sport 2813 is the compact version at 28.92 ft, 17,650 lbs dry, 20,500 lb GVWR, with two slides, a queen bed, a full rear bath, 320Ah of battery, a 5,500W Onan generator, and washer-dryer prep at $237,580. The Winnebago Vista 33K stretches 34.25 ft on a 22,000 lb GVWR with two slides, a king bed, a bath-and-a-half layout, and 50-amp shore power at $208,885.
The Bay Star Sport 2813 carries 75 gal fresh, 60 gal grey, 40 gal black, and 25 gal LP; the Vista 33K bumps those to 93 gal fresh, 102 gal grey, 75 gal black, and 18 gal LP. For $28,695 less, the Vista 33K delivers 5.33 ft more length, a king bed, the bath-and-a-half, and 1,500 lbs more GVWR.
Verdict: pick the Newmar Bay Star Sport 2813 for Newmar build quality and shorter exterior length in the Class A class; pick the Winnebago Vista 33K for substantially more interior, larger tanks, and the bath-and-a-half at a $28K savings.

Pick the Newmar Bay Star Sport 2813 if…
Buyers who value the Newmar nameplate and want a 29-ft Class A that fits state-park sites the 34-ft Vista 33K can't access. The Bay Star Sport 2813 carries Newmar's reputation for full-paint exteriors, fit-and-finish, and resale value, plus standard washer-dryer prep, 320Ah of batteries, and a 5,500W Onan. At $237,580 it costs $28K more than the Winnebago Vista 33K but delivers tighter maneuverability and the brand reputation that holds value over 7-10 years.
Pick the Winnebago Vista 33K if…
Couples and small families who want maximum space and a bath-and-a-half at the lowest Class A price possible. The Winnebago Vista 33K stretches 5.33 ft longer, adds a king bed and 1.5 baths, and carries 102 gal of grey water for longer dry-stay stretches, all for $28,695 less than the Bay Star Sport 2813. Best for buyers prioritizing interior space and toilet count over brand name; tow capacity 5,000 lbs handles a small SUV dinghy.
Frequently asked
Is the Newmar build worth $28,695 more?
Newmar typically holds 5-8% more resale at year 5 than Winnebago. If you keep it long term, the price gap narrows; for 3-year owners, the Winnebago Vista 33K's lower depreciation start saves more on the resale side.
Why does the Bay Star have more LP but less water?
Layout choice. The Bay Star Sport 2813 dedicates more bay space to 25 gal LP for cold-weather furnace and stove use; the Vista 33K prioritizes 93 gal of fresh water for off-grid stays.
Can both fit a king bed conversion?
Bay Star Sport 2813 ships queen and would need a custom job for king upgrade. The Vista 33K ships king bed standard, no modification required.
