I get your point, but those tow numbers are notoriously optimistic. Most people I bet would not be comfortable towing 4000 lbs with a Maverick, and it would struggle on grades or in heat. You can even feel that kind of weight with a full-size truck. Above 5000 lbs in most places you need independent trailer brakes.

The real issue that limits the Maverick for a wider audience is the rear is too small to comfortably fit kids, especially in car seats. Adding 4 in of leg room to the rear and making the whole truck 4 in longer would've made in a great homeowner family option without sacrificing much agility.
