Fuel mileage 5th wheel vs travel trailer

To answer some of the questions in this topic. The truck has a cover on the bed to keep wind drag down. The first trip out was a 300 mile round trip to a campground we go to couple times a yr. With in the same state of Michigan. Speeds of 62 to 65. Mid grade gas. All same factors that we did with the 5th wheel. My thought would have been with less weight-1500 pounds and lower trailer, better gas mileage. I have to wonder if the difference being hitch over the wheels sets up different than just dragging it behind you. Leaving for 2500 mile trip next week we'll see what this shows..

I watched a show once (mythbusters?) where they illustrated that truck bed covers actually make MPG worse. Something about an open bed creating a "ball" of air that forces air up and over as opposed to a covered bed which created more down force. As far as MPG trailer vs a FW, I would guess MPG has more to do with the Tow vehicle, terrain, wind, and driving habits than splitting hairs about which type of condo you are pulling - lb for lb of course.
