Capacities have nothing to do with size classes. The Tacoma and Frontier can tow more than 5000 lbs and their payload capacities are close to the Ridgeline's as well. That doesn't make them full size trucks. The Silverado is 225 inches long. The Frontier crew cab is 205 inches, the Tacoma (with short bed) is 208 inches. Honda hasn't released final specs yet but I'll give you 35 to 1 odds the Ridgeline's length doesn't top 210 inches. That's not full size.
