I don't own the trailer so that's out. Pittsburgh power makes a muffler for my truck and a system that is suppose to remove the air from the diesel fuel. A performance muffler I know would make a difference. Its not that expensive either only $158. They claim .3 mpg gain. The other part, the air removing system, I am a little skeptical about. After talking with my step-dad who works in the fluid and filter division at Cat, and also has a master degree in chemistry doesn't see that system working as is, although it can be done. Any comments?

As far as slowing down, i usually only run 62-65 mph. I work for an expedited freight company so time is usually an issue. If I slow down to much I would have trouble meeting time deadlines.

If I can stay around 62-63 mph I can get around 6.2-6.5 mpg
