Sadly, a tow rating of 2000 lb doesn't mean you can tow 2000 lbs for long days, at any altitude, up and down whatever hills and mountains you encounter. As with any mechanical thing, you need to leave some margin between what you intend to do, and the machine's eventual failure point. For a 2000 lb rating, a trailer weighing something like 1500-1600 pounds LOADED might be a realistic limit.
Beyond that, trailer manufacturers understandably publish the "Dry Weight" of a trailer, meaning the weight before the owner adds any options (like an air conditioner), and before the owner adds any of his own "stuff", like food, clothes, bedding, water, propane, tools, etc, that also increase the weight that your vehicle will have to tow. (Some mfrs, like Rpod, publish a UVW, which is similar to Dry Weight, though not substantially different. The lightest Rpod has a UVW of 2500 pounds.)
Beyond that, vehicle manufacturers are good at hiding the fact (though it is disclosed in the fine print) that their stated tow rating is reduced pound-for-pound by any weight you put in the tow vehicle itself, including cargo in the bed and people other than the driver.
And finally, I think your Maverick has a CVT. I recently asked my favorite professional transmission shop what they think of modern CVTs, and their answer was "Well, they bring us a lot of business". Take that however you want.
MPG is not the most important spec.
