I understand perfectly where you are, and would LOVE to buy an Escape in principle but would have a hard time pulling out the checkbook. If I were in your position, I would do my best to determine how much of the Internet noise is based on a small percentage of unhappy owners vs a large percentage of owners. Ford is selling a LOT of Escapes and people I know who own them are delighted.
I think mileage is gonna be based on how heavy you put your right foot into the throttle. Won't the EcoBoost even run on regular gas?
Like I said, 3500 lbs. of advertised towing capacity is where I would want to be if I wanted to tow anything regularly, even 1500-2000 lbs. But I completely understand where you're at, having owned Fords, Hondas, Acuras, Mazda, SAAB's, multiple GM, Chrysler, AMC, BMW, and various brands of English cars over 43 years....oh and a Toyota FJ40 Land Crusher and my Foz...
Good luck--I try not to bring prejudice into the equation. How about a 2013 Forester XT with 2400 lbs of capacity? You would have to settle for an old 4 speed automatic, but I spent the day at the Subaru dealer today, sat in everything they had on their lot, an still like my '09 Foz the best (maybe because the memory foam seat is shaped just like my butt and my spine).
Good luck,
George
