Newmar Bay Star Sport 2813 vs Winnebago Sunstar 33K
2026 Class A comparison · side-by-side specs, verdict, and who each is best for.
Quick verdict
These Class A motorhomes share the Ford F-53 chassis and 7.3L V8 powertrain but split on length and amenity philosophy. The Newmar Bay Star Sport 2813 sits 28.92 ft long at 17,650 lbs dry, with two slides, a queen rear bed, a single full bath, 75 gal fresh, 5,500W Onan generator, 320Ah of batteries, and washer-dryer prep at $237,580. The Winnebago Sunstar 33K stretches to 34.25 ft on a 22,000 lb GVWR, bringing a king bed, bath-and-a-half layout, 50-amp shore, and 93 gal fresh at $208,885.
Tank capacities favor the Sunstar 33K substantially: 93 gal fresh (vs 75), 102 gal grey (vs 60), 75 gal black (vs 40), but 7 gal less LP (18 vs 25 gal). The price gap of $28,695 buys the Sunstar's longer floorplan and king plus 1.5-bath layout over the Newmar's badge and tighter exterior.
Verdict in the Class A category: choose the Newmar Bay Star Sport 2813 for Newmar's build quality and 29-ft maneuverability; choose the Winnebago Sunstar 33K for substantially more space and tankage at the lower price.
