I have the same truck - don't be deceived by the 3.2L V6. The Ecoboost is a powerful motor. Unfortunately our trucks don't have much payload :-(
I know jayco web site calls this 5er a half ton hero. On paper there could be enough payload to tow this trailer. My feeling is once the TV and TT are loaded, it could be a miserable towing experience and possibly dangerous. Not due to the engine, but the light payload of our half ton trucks.
Trading off a new truck sounds like a loosing en devour. Towing the 5er with this truck also seems risky.
I'd either keep the truck and look at a travel trailer. Or trade the truck for a 3/4 ton + and pursue the 5er. Good luck!
