I have a 2014 F 150 with a 3.5 Ecoboost, it will two your 10,000 lbs trailer just fine and even better if you put LT E rated tires and add airbags to the rear axle. Those two alone will bring the truck to its full potential and beyond. I drug a 3 horse slant load heavy steel bumper pull trailer all over Southern Illinois and have since gone to a Corn Pro 3 horse gooseneck (16' floor) horse trailer. The truck handles this one, even being heavier, better than the bumper pull I used to have.
I've often drug equipment or dump trailers around in the 8-12,000 lbs range. I will continue to use my F 150 because I have it, it is well beyond paid for, it is in good shape with low miles and does the job fine, but my next truck will be a 3/4 or 1 ton. I wouldn't be shy of a 6.2 or 7.3 gas V8 for what you are going to do, they are both good engines and take alot of abuse.
