Welcome.. I have had my Ecoboost sense last fall and I have towed alot with it, pulling a heavy travel trailer over steep mountain passes IT'S GREAT I can go up passes at any speed and never run out of power. You are going to love the power it already has. And if you take it easy on it you'll get great gas mileage, I get 21.6 most weeks to and from work part city mostly hwy. and up to 24 mpg on a long road trip if I stay around 60mph. Looks like you picked out a really great truck, have fun.
