The answer about the MPG is............it depends.
As others have said, once you get a trailer up to speed on a flat road weight does not really come into play. Aerodynamics are what counts.
In the hills and mountains are a different story.
The horse power formula is lifting a certain amount of weight in a certain amount of time. When you are going up hill with a trailer on, you are lifting that weight. The more weight you have the more HP you will use to lift that weight. The more HP you use the more fuel you will use.
So the answer is......it depends. If you spend a LOT of time towing in the hills and mountains a heavy trailer will cost you in fuel. On the flats, it makes very, very little difference.
