The Triton Boats 220 T Xtreme 2007 is a pontoon design and the Triton Boats DV 17 Magnum 2008 is a deep-V design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
Size is the most obvious dividing line here. The Triton Boats 220 T Xtreme 2007 measures 22,0 feet overall (2007), giving it roughly 5,0 additional feet of deck space compared to the Triton Boats DV 17 Magnum 2008 at 17,0 feet (2008). Weight tells a clearer story for trailering families: the Triton Boats 220 T Xtreme 2007 tips the scales at 2 086 lbs - 986 lbs more than the Triton Boats DV 17 Magnum 2008 at 1 100 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 150 hp, the Triton Boats 220 T Xtreme 2007 has a 25-hp advantage over the Triton Boats DV 17 Magnum 2008's 125-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads - 27 gal and 24 gal - so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Triton Boats 220 T Xtreme 2007 is rated for 11 passengers, while the Triton Boats DV 17 Magnum 2008 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Triton Boats 220 T Xtreme 2007 could be the deciding factor.
Bottom line: Choose the Triton Boats 220 T Xtreme 2007 if your priority is putting more people on the water - it handles 11 passengers and at 22,0 ft it has the deck room to back that rating up comfortably. The Triton Boats DV 17 Magnum 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
