A Maverick is hardly a working truck. It's got the same towing capacity of an older Kia Sportage. It's got front wheel drive (or awd). It's a car with a bed, not a truck.
Really the only thing I think you can ding it for is the small bed. It used to be that trucks this size would have a regular cab or an extended cab with the two tiny side facing seats, and they would have a longer bed. With the tailgate down you can still move sheet goods with a Maverick though.
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.
I agree that the Maverick's bed is small and the back seat is small. IMO they would have been better off making a regular cab or an "access cab" thing with two doors and fold-down seats, and used the extra length to add to the bed. Those are great if you're single or don't have kids, and you just need to carry passengers very occasionally. If you're regularly hauling kids around you definitely want the next step up. A lot of tradesmen essentially never even use the passenger seat though, and the back seat is just lost bed space unless you're using it for locked storage.
The Maverick only tows 2000 base, the 4000 is an upgrade package and only for trailers with their own brakes.
RWD is pretty functionally important for a vehicle to maintain control while towing significant weight, as all the weight sits on the back of the frame, and that's where you want the engine power to go.
The Maverick is not a working truck, which was my original point. In terms of what matters, it is worse in every way than a 40 year old design.
You can't really compare the tow ratings with a 1985 Ranger. Back then the ratings were not standardized and were generally inflated for marketing purposes. Today tow ratings are standardized by SAE J2807. The Maverick has way more power than the old Ranger and weighs about 600 lbs more, plus it has trailer sway control. You're going to have a much easier time towing 4000 lbs in the Maverick than the Ranger.
Edit: The Maverick also has 300 lbs more payload capacity than the 1984 Ranger. The fact is, not everyone needs a giant heavy truck. I see loads of tradesmen driving Mavericks.
Grabbed it in '25 with factory warranty still on it for about the price of a new maverick.
It's a car with a bed, not a truck.
I've seen plenty of people in working clothes driving them, carrying working tools and such.
How often do you need to pull 2000kg?
Towing weight is also a good proxy for frame strength. I do some light forestry work moving and bucking logs, freeing stuck cars, plowing snow in addition to towing trailers and equipment.
Plus, you can't really put a winch or snow plow on a Sportage.
I always find it kind of surprising how large a vehicle people in the US think they need to pull trailers, especially when you compare with the size of trailers people pull in the UK. My own elderly Range Rover (1990s P38A) has a plated towing weight of 3500kg which means you can pull another one on a trailer with it easily. With the back full of tools and spares and a couple of passengers, you've got an all-up weight well over six tonnes!
