Frontal Area is an absolutely massive factor.

We have a 6x12 trailer that we’ve done a minimal RV conversion on. It rings in at 1300lbs empty. Maybe 1500 loaded. However, it’s 6.5 feet tall.

Towing that cuts our SUVs fuel economy from 25 mpg to 10 mpg at highway speeds. In the winter, we’ve had it drop as low as 6 mpg.
