I had the 2015 with the 3.5 and after it got soaked through the A pillars, the dealer bought it back and I bought a 2016 with the 2.0 turbo ecoboost. I didn't tow anything with the v6 but have towed a motorcycle trailer with 700 lb bike over 3000 miles through Utah, Colorado, Wyoming and Montana. The only time I had any problems with it was coming west out of Jackson Hole. Pushing it pretty hard over the pass and it went into emergency mode the last 1/2 mile to the top of the pass. Within minutes it had cooled down and has been fine since. We averaged 18.5 mpg for the 3000 mile trip.
