The little engine that could
We tow our 2012 21FBRS with an F-150, 3.5 EcoBoost, 3.73, weight distributing hitch and friction anti-sway. Definitely overspec for the little trailer. I believe safety is the highest priority, then easy to enjoy the trip. We see 12-14mpg at 55mph highway.
The EcoBoost torque is best at low rpm, best mpg. Your small V-8 will require higher rpms to pull the trailer. You will know it's there with the small V-8, though your rear gear will help.
Get the right hitch, setup correctly (an expert), do not exceed the load capacities for the TV and TT and you should be OK.
