Matching a tunnel Caddo Deckliner 183 OB Tunnel Hull 2010 against a modified vee Caddo Runabout 184 XL BR IO 2010 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
On paper these two are close siblings in the size department — Caddo Deckliner 183 OB Tunnel Hull 2010 at 18,3 ft versus Caddo Runabout 184 XL BR IO 2010 at 18,4 ft. At 32 lbs and 33 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 190 hp, the Caddo Runabout 184 XL BR IO 2010 has a 40-hp advantage over the Caddo Deckliner 183 OB Tunnel Hull 2010's 150-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Caddo Deckliner 183 OB Tunnel Hull 2010 carries 46 gallons versus 25 gallons in the Caddo Runabout 184 XL BR IO 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Bottom line: Choose the Caddo Runabout 184 XL BR IO 2010 if your priority is putting more people on the water — it handles 8 passengers and at 18,4 ft it has the deck room to back that rating up comfortably. The Caddo Deckliner 183 OB Tunnel Hull 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
