The reason for a lowered truck to be more efficient is having less frontal area, less resistance. And maybe less weight if it is the case. But this is considering you are comparing to identical trucks. There are no identical trucks in the site since one of the variables is the owner, and we are all very different. VERY!!!
The only place we could get a fair comparison between different trucks is in a close enviroment like a laboratory and we are too uncontrolable
to be submmited to this.
So the best we are going to get here is what each one of us is going to post regarding their own truck. To compare this with a truck 1000 miles away is another story.
