I’d like to know why you think they’re not in the same category as both are:
unibody, not body on frame.
four door crew cab
small bed
Limited capacity, compared to a “real” pickup truck
With the center console in the rear seat, the Baja can only seat four compared to the Ridgeline’s five. The Ridgeline can tow significantly more; bed weight capacity is a bit more as well.
Obviously the styling is wildly different: the Baja is based of a decades old gen station wagon, whereas the Ridgeline is following the modern big beefy SUV trend. Maybe that’s where you’re coming from?
