Both the Avalon Paradise - 20 Foot 2008 and the Avalon Paradise RC 22 ft. 2010 are pontoon designs, both built in aluminium, so the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
On paper these two are close siblings in the size department - Avalon Paradise - 20 Foot 2008 at 20,0 ft versus Avalon Paradise RC 22 ft. 2010 at 22,0 ft. Weight tells a clearer story for trailering families: the Avalon Paradise RC 22 ft. 2010 tips the scales at 2 050 lbs - 180 lbs less than the Avalon Paradise - 20 Foot 2008 at 1 870 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 125 hp, the Avalon Paradise RC 22 ft. 2010 has a 25-hp advantage over the Avalon Paradise - 20 Foot 2008's 100-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads - 36 gal and 36 gal - so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Avalon Paradise - 20 Foot 2008 is rated for 12 passengers, while the Avalon Paradise RC 22 ft. 2010 caps at 11. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Avalon Paradise - 20 Foot 2008 could be the deciding factor.
Bottom line: Choose the Avalon Paradise - 20 Foot 2008 if your priority is putting more people on the water - it handles 12 passengers and at 20,0 ft it has the deck room to back that rating up comfortably. The Avalon Paradise RC 22 ft. 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 11 that costs less to run day-to-day.
