I rented a U-Haul 5 X 9 ramp trailer. That thing was a freaking parachute. Mileage at 55 MPH dropped from about 33 down to slightly over 19. Mileage at 30-40 MPH dropped from 30 down to 20 in one direction, and dropped from 36-37 down to 23-24 in the other direction (upwind vs downwind).

I blame that ramp sticking up in the air, possibly aggravated by airflow directed down by the aero topper. Good thing I only needed to drive about 60 miles, but it still messed up mileage for that tank.
