I do agree that there is a negative effect on aerodynamics at the back of a vehicle that reduces fuel economy. That's why you see some large tractor trailers with those "tails" to smooth the airflow at the rear of the trailer. That being said I would think its not a one shoe fits all when it comes to a pickup. Cab design and bed length, I would think would play a role in the air flow over the bed and tailgate. Either way I haven't found a significant difference with the tailgate up down or with a bed cover.
