Gary is correct i wasn't picking on the Ecoboost i wouldn't pull that trailer with my half ton either unless i had too.
No 1/2 ton is really designed for the length of some of these lightweights - yes capabilities and pulling power has increased but when they say MY XXXXXXX can pull 1million pounds and blah blah blah they are not "lying" what they fail to say is, its pulling a trailer loaded with a weight that's in a controlled environment ,
on a flat surface, with no wind, at the right temperature, etc, etc, etc, they are not real world conditions and if for some reason that long long trailer gets out of control its like a giant pendulum effect, and it can and will wag the dog as Grassy says - i drive upwards of 60,000 miles a year (I'm an Area Sales Manager for the largest aftermarket auto parts distributor in Canada) and I've seen a lot of wagging
cheers
