Looking at 2013 F-150 EcoBoost - any concerns?

I've not had any problems with my 2011 EgoBoost. But the rear tires seem to be wearing out fast, I think I push down on the right pedal too hard at times. I'm getting about 19mpg unloaded, about half that towing. I've read of the "condensation in the intercooler" problem but mine is a gem. I did buy the extended warranty due to first year engine worries. So far so good.
I'd buy another.
Good luck with your choice.
