The driver probably has more to do with your mpg than any other signal factor. One thing you could do is slow down and try to plan your stops. Drive like you have an egg under your accelerator pedal. Speeding up and slowing down can eat up your fuel. If you pull a van and own the trailer you could install a bubble on the front of the trailer. There are also wind deflectors that are also supposed to help with wind resistance.
