This whole thread reminds me of the release of the 190 series Yamaha boats. At that time, 90% of us owned a 20' or larger boat. So the overwhelming response was what the hell is Yamaha thinking. But we all had to remind ourselves that we (as current owners) were not the target market. But it didn't mean it didn't exist.
So asking in this forum if a Maverick should be used for towing, of course the overwhelming response will be hell no. As none of us could use it to pull our current boat. That doesn't mean the market doesn't exist, just not in this crowd.
Since my first new Pontiac Grand Am in 1995, I have had a receiver hitch on every vehicle since. My tow vehicle grew with my toy sizes. As long as someone knows how to calculate gross vehicle weight in comparison to tow capacity, they can use them and be safe. 4000lb is more than enough for many owners. Again, many pull utility trailers and will never own a 20'+ boat.
I started with a waverunner, which expanded to two, to a Shuttle Craft, to a 20ft SeaDoo X20. And the tow vehicles always had to scale to the load. In fact, we walked away from our first Yamaha due to it's size next to my second Chevy Colorado. It was within tow capacity, but I could not get over how that boat dwarfed my truck.
So yes, it will be a good tow vehicle. And for those that question it due to it's CVT powertrain, or hybrid or electric power plant need to leave these vehicles to those that are early adopters and trust the Ford Warranty. As if they use it as it is rated, Ford should back them up if it cannot perform as rated.
Love them or hate them, Ford is known for quality products (nobody really makes crap anymore) so why would they risk that good name by over rating a new to market vehicle? I would have no issues pulling a couple waverunners, a couple sleds etc with this vehicle. But I don't expect a full electric to take on in our climate as much as a hybrid will. (the reason I tell myself why I am not ordering a GMC Hummer, HA!)
