The Campion Allante A20 IO BR 2022 vs Campion Allante A20 OB RB 2022 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
On paper these two are close siblings in the size department — Campion Allante A20 IO BR 2022 at 21,6 ft versus Campion Allante A20 OB RB 2022 at 20,0 ft. Weight tells a clearer story for trailering families: the Campion Allante A20 IO BR 2022 tips the scales at 3 400 lbs — 1 054 lbs more than the Campion Allante A20 OB RB 2022 at 2 346 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.
The power gap is worth calling out. Rated to 350 hp, the Campion Allante A20 IO BR 2022 has a 50-hp advantage over the Campion Allante A20 OB RB 2022's 300-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 42 gal and 42 gal — so range won't be a tiebreaker here.
Both boats are rated for 6 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: Performance buyers should lean toward the Campion Allante A20 IO BR 2022 and its 350-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Campion Allante A20 OB RB 2022 with its 300-hp rating is the more economical daily driver.
