The total package is less aerodynamic, the 5er has smoother air flow than a PU and TT.
True story, can't fool physics.
And there could be other more subtle differences that contribute to fuel mileage as well.
However I seriously doubt 3mpg difference simply due to the trailer.
I don't get 3 mpg different or anywhere near that much between hauling the TC. TC & 6klb boat. Boat by itself, or 32' v nose enclosed trailer.
What can and sometimes does make that magnitude of difference though is ground speed, terrain, altitude, fuel type and wind speed/direction.
Caveat, I'm not an obsessive fuel mileage checker. Generally I may flip to the mileage screen during a trip, say, "Yup getting bad mileage..." and flip it back to the compass/temperature screen.
