I took all of the equipment off of my trailer yesterday because I had to go and pick up some 12 foot long items for the house. Normally I get around 13 MPG with the equipment loaded up on the trailer. I figured that since I removed about 1800 pounds, give or take a few pounds, that my mileage would jump up to around 15 to 16 MPG. Boy was I surprised when the mileage actually dropped to 12.5 MPG. I think that even though the gate is made up of expanded metal, it is still acting like a big old sail and creating a lot of drag. When the mowers are on the trailer, it breaks up the wind and reduces the drag. I'm going to take the gates off of the trailer today and see if that makes a difference. If my mileage jumps up I'm going to try to make some sort of deflector to try and get the air up and over the equipment and tail gates on the trailer. The point of all of this is to try to get better gas mileage. Just switching from my 1995 F150 to this 2007 Chevy 1500 resulted in a 30% increase in fuel mileage. The Ford got 10 MPG and the Chevy is getting 13 MPG. I had seriously considered going to a 12 foot trailer with a single axle because of the reduced weight. But if weight is not the problem, then the tailgate must be. What do you guys think?
