Sorry to hear about the misfortune with your rig!
I've been towing my Eagle 266RKS with my 2011 F-150 Ecoboost for 4 years now, and I'm very happy with it. My truck is virtually identical to yours, but you probably have the newer, beefed up Ecoboost - which generates even more horsepower & torque than mine. If your trailer weight is properly distributed and your WD Hitch is properly set up, you shouldn't have any problem. That being said, keep an eye on your total payload. That's where 1/2 ton truck generally run into problems.
Good luck with your new rig, and Happy Camping!
