I've had mine for just over a year now and do miss my Dmax when it comes to towing but am not completely disappointed with the ecoboost. We did a 4500km trip this past summer
2013 Vacation route The only problem I encountered was the trany temp hitting 230F on the digital display pulling slowly through CO with an out side temp of 67F, while the gauge was reading norm. I also had some concerns on long down hill grades that only allow 25mph. I had to ride the brakes quite a bit and the engine braking had little to no effect in 1st/2nd gear. It is quite able to pull I find and altitude didn't affect its ability. If I was able to go back, I'm still not sure I would have kept the Dmax for the the 5/52 weeks we pull in a year, especially in winter where we reach -35C frequently with a 7km commute to work one way.....
