The Campion Allante 545i BR 2011 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 545i BR 2011 at 20,2 ft versus Campion Allante A20 OB RB 2022 at 20,0 ft. Weight tells a clearer story for trailering families: the Campion Allante 545i BR 2011 tips the scales at 2 886 lbs — 540 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 300 hp, the Campion Allante A20 OB RB 2022 has a 75-hp advantage over the Campion Allante 545i BR 2011's 225-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Campion Allante A20 OB RB 2022 carries 42 gallons versus 29 gallons in the Campion Allante 545i BR 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Campion Allante 545i BR 2011 is rated for 8 passengers, while the Campion Allante A20 OB RB 2022 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Campion Allante 545i BR 2011 could be the deciding factor.
